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.

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.

If a hook encounters an error or warning, it will show up as a notification.
The currently available hooks are:
- past-date-warn
Warn if Date header value is far in the past or future.
- important-header-warn

- missing-attachment-warn
Warn if Subject, draft body mention attachments but they are missing.
- empty-draft-warn
Warn if draft has no subject and no body.
They can be disabled with [composing.disabled_compose_hooks] setting.
- Add character attribute support
- Add cursor key mode support
- Fix buggy set fg / bg sequences
And added a bin under tools to test arbitrary apps using the embedded
terminal:
cargo run -p tools --bin embed -- "htop" 2> .htop.debug.log
