Consensus is that explicit imports make it easier to understand the
example code. This commit removes the prelude import from all examples
and replaces it with the necessary imports, and expands other glob
imports (widget::*, Constraint::*, KeyCode::*, etc.) everywhere else.
Prelude glob imports not in examples are not covered by this PR.

In a recent commit we added Rec::split, but this feels more ergonomic as
Layout::areas. This also adds Layout::spacers to get the spacers between
the areas.
Simplified a bunch of the logic in the demo2 example
- Moved destroy mode to its own file.
- Moved error handling to its own file.
- Removed AppContext
- Implemented Widget for &App. The app state is small enough that it
doesn't matter here and we could just copy or clone the app state on
every frame, but for larger apps this can be a significant performance
improvement.
- Made the tabs stateful
- Made the term module just a collection of functions rather than a
struct.
- Changed to use color_eyre for error handling.
- Changed keyboard shortcuts and rearranged the bottom bar.
- Use strum for the tabs enum.
