My Key_Event is disabled (yet).
-Changed it to only toggle the console with ESCAPE when you're in the console,
 so binding toggleconsole to a normal key wont toggle it while typing.
-Changed the panic console key to shift-escape since ctrl-escape open the start
 menu.
Feel free to test it.
@ETG: since I can probably only reach you this way: it is intended that the console
toggle key now appears in the console input line and is also send to e.g. message.
This is because the color tag ^ key opens the console on some keyboard layouts and
couldnt be typed in otherwise.
