Alexey Minnekhanov:
- Registry keys are created if they don't exist
- "Custom colors" are stored in the registry too now (tested to work under
Windows XP)
- Fixed a check during adding of a new wallpaper to the list. Now it will actually deny
addition of the same wallpaper image more than once
- Some TAB -> Spaces fixes
