md3 tag attachments (implemented but untested), also the capability to attach any entity to any other entity without tags (I.E. Q2 vwep models should work if attached to tag "")

this may have fixed some unknown bugs regarding viewmodels and such (I hope so, it's cleaner, although more complicated)
