[physfs] Password protected files.

I am using Physfs in some software at the moment. It is a GUI builder, the
end users can now "publish" their GUI to a single file (ZIP) that they can
distribute to other users. Physfs has been great in letting me implement
this. I would also like to give the developer the capability of protecting
their published GUI.

All the best,

Tony.
