This program is a hack. To be able to hook into the FIFE map editor load and
save functionality we have to change the import path. It runs the FIFE
editor such that our custom loaders and savers are used instead of the stock
FIFE ones. Ideally the FIFE editor could be extended to support custom loaders
and savers so we don't have to resort to tricking the editor. :)
