When in raw mode, go to level 2, but use level 1 for cooked
so that we don't obfuscate ctrl-c.
A consequnce of this is that CTRL-C is now reported to the app
as CTRL-lowercase-c where we previously reported as CTRL-uppercase-C.
Made a note of the breaking nature of this change in a new changelog
file.
Fixed recognizing SHIFT-TAB

This doesn't really change any behavior, but adjusts the types
such that CSIs that set colors have the potential to track the
alpha channel and that can make it through to the GUI/render layer.
We need to force the codepage to UTF8 this to avoid having our UTF-8
bytestreams be misinterpreted, and to restore the original before we're
done.

implement missing alt-screen support and fixup building the examples
while we're in here.

It's been replaced with an opaque termwiz error type instead.
This is a bit of a more conservative approach than that in (refs: #407)
and has less of an impact on the surrounding code, which appeals to
me from a maintenance perspective.

This commit adds a simple example of nested widgets, which uncovered
an issue with respecting the layout positioning, and adds a secondary
screen buffer to make the widget render cycle more optimal:
```
cargo run --example widgets_nested --features widgets --release
```

This restructures the LineEditor to allow the hosting application to
override key presses and apply custom edits to the editor buffer.
Methods for performing predefined actions and for accessing the line
buffer and cursor position have been provided/exposed to support this.
One consequence of this change is that the editor instance needs to be
passed through to the host trait impl and that means that the LineEditor
can no longer be generic over `Terminal`. Instead we now take `&mut dyn
Terminal` which was how the majority of non-example code was using it in
any case. This simplifies a bit of boilerplate in wezterm but adds an
extra line to the most basic examples.
