This allows setting up shortcuts relative to the final tab in
a window, rather than always being relative to the first.
The default assignment for CTRL+SHIFT+9 is now `ActivateTab=-1`
as a convenient way to always reach the last tab.

Bound to CMD-K and CTRL+SHIFT-K by default. This also functions
while the output is filling up (eg: `find /` and hit the key binding
to keep pruning the scrollback).

Now that the toml file support is removed, we can directly
express the key actions as enum variants so remove this
intermediate type and use the enum directly.
This commit adds the ability to change the relative or absolute
position of a tab within its containing window through the
use of a key assignment.
We include a default assignment of CTRL+SHIFT+PageUp for moving
left and CTRL+SHIFT+PageDown for moving right.
