Fix bind commands getting run when closing UI

Introduced in commit "Add togglemenu command" bf2b04.

Don't let UI key event changing key catcher affect bind parsing. Bind parsing itself will never change the key catcher.

Example of issue: if mouse1 is bound to +attack when clicking Resume Game, player will shoot until releasing the mouse button.
Mouse button should have to be released and pressed again before player will shoot.
