Subject: init: Deactivate Terminal tab switching hotkeys outside of Terminal

The bindings I created to switch tabs in Terminal shadowed shortcuts in
all other applications, preventing them from performing their normal
function.

To get the bindings only in Terminal, add an application watcher that
enables and disables them when Terminal is activated and deactivated.
