- made everything compile properly on windows again - removed libanim/libvmath, we'll use them as external dependencies - added new maxgoat_stub 3dsmax plugin project. Gets loaded as a max plugin and loads the actual maxgoat (and later maxgoat_anim) exporters on demand, to allow reloading the actual exporters without having to restart 3dsmax (which takes AGES).
