preliminary work on really cleaning up *model.c. atm, just split out the model

Browse source 
type specific code into the appropriate files (which will later be merged as
much as possible) and remove all model type specific code from model.c.
gl_model.c is no more as it ended up being an exact copy of model.c minus a
header include and a prototype, neither of which were needed.
