DFO Toolbox & npk2gif 0.2.0

This is the first release of DFO Toolbox, a GUI application for viewing and extracting the contents of DFO's .NPK files. It doesn't really do anything better than DNF Extractor at the moment. This is an early release for those interested to try it out and give feedback.

npk2gif, a command line tool for creating animated GIFs from .NPK files, is included. The only change from the 0.1.1 release is that it no longer errors when reading certain frames unlikely to be used in GIFs.
