This logic is redundant with the addition of tcell-term and the main

The MouseEvent method of the composer passes on the mouse event to it's
underlying grid while the composer is locked. The underlying grid then
passes on the mouse event to child objects of the grid, which are
referenced via fields of the composer (c.editor is a field in composer
but a child of c.grid, for example). When the grid attempts to pass on
the mouse event, it is referencing a pointer which is locked, and a
deadlock occurs due to the original lock in composer.MouseEvent.
Unlock before calling the grid.MouseEvent, and lock the composer again
after it is called.

The terminal widget uses it's own redraw logic to improve performance.
With the addition of a main event loop, the redraw logic can happen in
the main loop via the standard Invalidate logic.
Use the Invalidate method to mark aerc invalid, and immediately trigger
a redraw with ui.QueueRedraw. The follow up call to QueueRedraw is
needed because the terminal update happens in a separate goroutine. This
can result in the main event loop finishing it's process of the current
event, redrawing the screen, and the terminal having additional updates
to be drawn.
This fixes race conditions by drawing and calling screen.Show in a
separate goroutine.

When checking for an exKey, aerc inspects the key and the rune of the
event vs the exkey binding. Runes should only be inspected if the key is
a tcell.KeyRune. Some Ctrl-[:alpha:] keys report a rune in tcell, but
aerc does not have these bound to the keystroke definition. Only <C-x>
has a rune bound, and is one of the very few <C-> keys that can actually
be bound to exKey
Only compare the Rune field if the key is of type KeyRune. Otherwise,
compare the Key. Also compare any modifiers with the keystroke/key
event. These changes allow for any control or alt key combination to be
bound to the exkey.
Update documentaiton to reflect that the default keybind is ':', and not
<semicolon>

The exline widget works by matching actual keystrokes to a map of
keybinds, and if a match is found sending simulated keystrokes through
aerc. This has the effect of aerc thinking we are actually typing in the
expanded command, and aerc attempts to draw the completions. This
results in even basic navigation having two screen draws:
For example, pressing 'j' to select the next message (:next), draws once
for the initial key event and state change, and again after the
completion debounce timer.
Disable tab completion while aerc is simulating keystrokes. If the
exline still has focus after simulating keystrokes, restore tab
completion.

The terminal widget uses it's own internal event handler to redraw
itself for improved performance. The event handler draws, updates the
screen, and invalidates. The last invalidate is redundant: Invalidating
has the result of telling aerc to redraw the screen. A race condition
can occur where an event is emitted from the terminal and the terminal
is closed before the event is handled. This results in handling the
event after the terminal is closed, and a panic:
