Nux uses XInterAtom constantly as opposed to saving the results of XInternAtom when performing drag and drop

Nux needs to be refactored in GraphicsDisplayX11.cpp to own an Atoms class. This class must be instantiated per display server (offering a singlet for each server) and fetch/cache atoms by name. Ideally atoms will be fetched on demand, however any system is better than the current XServer round trip performed. Contact for additional question: DBO on irc.freenode.net
