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.

Submitting to NNTP/Usenet servers requires you to specify which news
groups the post/article is going to. This commit places all
extra_submission_headers from a backend (in this case only NNTP
implements this) in the composing form fields.

Instead of showing the nondescript tab names in the tab area,
use Subject or To: data from the draft in the composer and a subject
from the thread entries.

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.
