* Integrate Farside into Whoogle
When instances are ratelimited (when a captcha is returned instead of
the user's search results) the user can now hop to a new instance via
Farside, a new backend service that redirects users to working instances
of a particular frontend. In this case, it presents a user with a
Farside link to a new Whoogle (or Searx) instance instead, so that the
user can resume their search.
For the generated Farside->Whoogle link, the generated link includes the
user's current Whoogle configuration settings as URL params, to ensure a
more seamless transition between instances. This doesn't translate to
the Farside->Searx link, but potentially could with some changes.
* Expand conversion of config<->url params
Config settings can now be translated to and from URL params using a
predetermined set of "safe" keys (i.e. config settings that easily
translate to URL params).
* Allow jumping instances via Farside when ratelimited

Previously the load/save/apply buttons in the config menu were hidden
below all available config options and required the user to scroll to
the bottom to save changes. This made for bad ux, since for new users,
it isn't immediately apparent that selecting a new dropdown value, for
instance, doesn't instantly save the new setting. The new layout should
make it more clear that hitting "Apply" is required to save config
changes.
The config menu has gotten out of control recently, but rather than
reducing functionality, I'm just going to set a max height for the div
and allow scrolling within the menu.
Ultimately though this indicates that the app is getting a bit too
complicated (imo). Striking a balance between customization and
minimalism is less of a priority for me nowadays though, hence why I'm
willing to let it slide for now. At some point, maybe when there are
more contributors, it could be nice to refactor this in some way so that
it isn't overwhelming to new users who are looking to customize their
instance (that's just me speculating btw, I haven't actually heard from
anyone who thinks there are too many options in that menu).
Introduces a new config element and environment variable
(WHOOGLE_CONFIG_THEME) for setting the theme of the app. Rather than
just having either light or dark, this allows a user to have their
instance use their current system light/dark preference to determine the
theme to use.
As a result, the dark mode setting (and WHOOGLE_CONFIG_DARK) have been
deprecated, but will still work as expected until a system theme has
been chosen.
* Add custom CSS field to config
This allows users to set/customize an instance's theme and appearance to
their liking. The config CSS field is prepopulated with all default CSS
variable values to allow quick editing.
Note that this can be somewhat of a "footgun" if someone updates the
CSS to hide all fields/search/etc. Should probably add some sort of
bandaid "admin" feature for public instances to employ until the whole
cookie/session issue is investigated further.
* Symlink all app static files to test dir
* Refactor app/misc/*.json -> app/static/settings/*.json
The country/language json files are used for user config settings, so
the "misc" name didn't really make sense. Also moved these to the static
folder to make testing easier.
* Fix light theme variables in dark theme css
* Minor style tweaking
* Implemented new dark theme
Now uses a dedicated css file for all dark theme color changes, rather
than replacing color codes directly.
Color theme is from discussion in #60.
* Minor link color update
Full implementation of social media alt redirects (twitter/youtube/instagram -> nitter/invidious/bibliogram) depending on configuration.
Verbatim search and option to ignore search autocorrect are now supported as well.
Also cleaned up the javascript side of whoogle config so that it now
uses arrays of available fields for parsing config values instead of manually assigning each
one to a variable.
This doesn't include support for Google Maps -> Open Street Maps, that
seems a bit more involved than the social media redirects were, so it
should likely be a separate effort.
Config options now allow setting a "root url", which defaults to the
request url root. Saving a new url in this field will allow for proper
redirects and usage of the opensearch element.
Also provides a possible solution for #17, where the default flask redirect method redirects to
http instead of https.
The implementation of POST search support comes with a few benefits. The
most apparent is the avoidance of search queries appearing in web server
logs -- instead of the prior GET approach (i.e.
/search?q=my+search+query), using POST requests with the query stored in
the request body creates logs that simply appear as "/search".
Since a lot of relative links are generated in the results page, I came
up with a way to generate a unique key at run time that is used to
encrypt any query strings before sending to the user. This benefits both
regular text queries as well as fetching of image links and means that
web logs will only show an encrypted string where a link or query
string might slip through.
Unfortunately, GET search requests still need to be supported, as it
doesn't seem that Firefox (on iOS) supports loading search engines by
their opensearch.xml file, but instead relies on manual entry of a
search query string. Once this is updated, I'll probably remove GET
request search support.
