Move the EWMH virtual desktop information get/set functions from the panel-plugin into the LuminaX11 library class.
Clean up the new desktopswitcher panel plugin a bit
1) Use the new LuminaX11 functions for desktop number get/set (which were moved out of here to there)
2) Streamline the createMenu function to only run the X11 calls once each - should make it a bit faster and more efficient.
