New tools build; morrowind and quake3 plugin updates

[mong...@icculus.org]

As you may have <a

morrowind NIF4 models import to freyja now. I've also provided a tool
to extract data from BSA pak files. Just make tools install-tools in
libfreyja/, and use the bsa utility.

bsa Morrowind.BSA

It has a cheesy shell like vfs interface. Commands are cd, ls, x,
help, exit. It should be clear how to use it. Note not all models
will load in freyja yet, since I haven't had time to test the entire
pak. =)

Quake 3 ( md3 ) export with animation is back. I had removed vertex
animation export, but now it's back. I had converted a few Ultima
Online, Jedi Knight II, and Quake2 models for the Quake 3 source
release... but JC canceled the source release. Oh yes, freyjautil is
useful for such things.

freyjautil legolas.glm md3 legolas.md3

Note that you won't get animation from skeletal animated files to
vertex animated formats as of this writing. Once the key framming
system is back up I can write such an autogeneration system.
