Remove USE_CDRTOOLS
Hide any external devices that are mounted on hidden directories in the file manager. These devices are generally for system-usage and not user browsing (such as the FUSE mountpoint for .gvfs)
Fix a bug with the taskmanager when multiple windows from the same application have the same title: make sure to properly select the window that was clicked.

While here, also apply the libLumina dependency order to give preference to the locally/recently compiles libraries during the build if possible in all the lumina tools.
Add a simple OSD to the audio/brightness up/down options in lumina-open (since these are what the keyboard shortcuts run). Also adjust the window list filter to cut out any "Lumina-" utilities that do not provide a custom window title (such as the OSD or other splashscreens).
Oops, forgot to add the new OSD background image to GIT.
