aerc: add quake-mode terminal

Add a drop-down (quake-mode) terminal which is a persistent terminal
session that overlays aerc at the top and can be toggled on or off.

Enable quake mode by setting [General].enable-quake-mode=true.

The height of the drop-down terminal can be set with
[ui].quake-terminal-height (default: 20).

Toggling is hardcoded to the F1 key. Note that this key should not be
used in your key bindings when you enable Quake mode.
