Fixed base project files and old app icon added

Before this version some files were missing so I coldn't import the
project to Momentics.  Also some uncessery files are beeing removed.
This should be fixed now. I also added the old Wallpaper Ruler icon ;-)
Ignoring binary files

We never put binary files on Git. Also ignoring a preview image
generated by momentics.
In case of doubt of which files should be versioned, just check the
Github examples from blackberry, like:

Diagram reviewed

Colored diagram correctly since our color blind friend cannot ;-)
Added the App Settings module.
