New preference option to use application GenericName (#80)

Merged simplejack-src requested to merge simplejack-src/xfce4-appfinder:use_generic_names into master

Added new preference option to use applications GenericName (freedesktop .desktop GenericName key) in place of their standard name. This is displayed only in the Icon/Tree View (tooltips and other areas continue to display the application Name).
