prev_entry, next_entry shortcuts (default bindings: Ctrl+p and Ctrl+n)
were not behaving consistently in all different listing index styles. In
particular in some conditions the switch entry shortcuts worked at most
once because the cursor position was not updated properly. This commit
fixes that.

Clear selection only when Escape is pressed, not after action is
completed. The user might want to perform further actions on the
selection.

If there are row_updates, it means we need to redraw. But in the draw()
call, we check is_dirty() to decide whether to proceed drawing. Add
row_updates not being empty into the dirty conditions.

Make Screen generic over its display kind: Screen<Tty> and
Screen<Virtual>. The latter is for "cached" renderings we want to keep
and copy to the actual screen when the Component::draw() method is
called. Only Screen<Tty> can write to stdout and it needs an stdout
handle.
Add a generation integer field to Screen, that changes each time it is
resized. This way, we can track if "stale" areas are used and panic on
runtime (in debug mode).
Introduce a new type, Area, that keeps metadata about a subsection of a
Screen, and the generation it came from. New areas can only be created
from a Screen and by operating on an Area to create subsections of it.
This way, it's impossible to make an area refer to (x, y) cells outside
the screen generation of its provenance. If stabilised this API should
eliminate all out of bounds accesses in CellBuffers.

So that if you select a mail/thread entry that is currently under the
cursor (making it `highlighted`) you can also see its `selected` status.

change_color() predated addition of Cell Attributes (Bold, Underline,
etc) so it didn't accept an attribute argument.
This commit adds a change_theme() function that does the same thing as
change_color() but also sets the cell attributes. It also takes a
ThemeAttribute as an argument instead of {fg, bg, attrs} individually.

We want to use SortOrder enum for non-thread purposes in the next
commit, so move it out of the thread module.
