Update Lumina-desktop to have a couple new systems:
1) Change the mouse cursor to have a "loading" icon when starting up an application. Return it to the original cursor as soon as a window is added to the taskmanager.
2) Add in the keybord-shortcuts framework. It appears that Fluxbox is intercepting the keyboard presses before Lumina can, so implement a custom fluxbox keys file specifically for Lumina.
Add the ability for lumina-open to take a couple simple command-line flags to perform simple system operations instead of just opening files.
Current flags supported:
-volumeup (volume +5%)
-volumedown (volume -5%)
-brightnessup (screen brightness +5%)
-brightnessdown (screen brightness -5%)

Also add a couple new functions to LuminaUtils in libLumina for reading/writing files.
Clean up the XDG application detection to support KDE's "loose" adherence to the standards, and remove any DE'exclusive applications from the system listing by default (so all the XFCE/KDE desktop configuration utilities will now be ignored, while the actual applications will still be available).
