App updates

After testing a windows version of the app I realised that it was difficult to quit the app. I decided to add the option of quiting the app using the escape key. This took longer than it should have but each time I use monodevelop I feel like I learn something new. In the emd I just had to input an if keycode function that equated to the function: application.quit. Once again I faced lots of grammatical errors with c#

Another problem after some user testing was the UI was not obvious enough. A lot of participants thought that you can only press the E key. I added the keys not used in the app to the
new UI but made sure they were't highlighted. Hopefully this will draw more attention to they keys available.
