The language_support variable is set to True by default,
and set to False in only 5 engines.
Except the documentation and the /config URL, this variable is not used.
This commit remove the variable definition in the engines, and
set value according to supported_languages length: False when the length is 0,
True otherwise.

use

The bing_news bug (discussed in #1838) was caused by wrong language tags, which
was fixed e0c99d9d / no need to change the bing_news search string.

This PR fixes the result count from bing which was throwing an (hidden) error and add a validation to avoid reading more results than avalaible.
For example :
If there is 100 results from some search and we try to get results from 120 to 130, Bing will send back the results from 0 to 10 and no error. If we compare results count with the first parameter of the request we can avoid this "invalid" results.
Add match_language function in utils to match any user given
language code with a list of engine's supported languages.
Also add language_aliases dict on each engine to translate
standard language codes into the custom codes used by the engine.
languages.py can change, so users may query on a language that is not
on the list anymore, even if it is still recognized by a few engines.
also made no and nb the same because they seem to return the same,
though most engines will only support one or the other.
If no language is specified, bing returns results with multiple languages
for one query which isn't really useful. Setting english as default
insted if nothing.
