Finally a usable "home" button for the n900. Great work!

A few bugs though
- short press camera => desktop doesn't work when in "multi-task view" mode (when u see all the running open programs". Or when in Menu view, when u see available apps to run
- short press camera => desktop doesn't work when the programming is still initializing. Eg run the 'terminal' app, usually takes 2 seconds to process before u can start typing anything. It ignores the short press during those 2 seconds the pogram 'processing circle' is running
