* Setting the window title via "-t" now works.

* Improved error message in case the initial shell couldn't be executed.
* Disabled setting the colors via arguments, mostly because it just did quit
  the app in case there were any arguments and no /etc/rgb.txt file. This
  allows Terminal to be used by the debug_server instead of MiniTerminal.
