3ds file support

We are almost done with 3ds file support. This is a MAJOR milestone in the project, as now we can load complex, textured models into our program. We have all of the major code already implemented, and now we are simply working out the bugs. At the time of this posting, it compiles with about 14 errors. Soon, we should have a workable version of the location file editor done. Once 3ds support is fully done, and we have the MFC location file editor, you can expect to see a substansial release with an actual, roamable environment, instead of just the empty plane we've been working with thus far.
