[Gtkradiant] misc_model modelscale key doesnt reflect changes in editor

[Jeremiah Sypult]

There is a problem with scaling models in GTKRadiant 1.2.1 01202002...
WolfRadiant, although unsupported, will show misc_models scaled
appropriately. Loading up mp_beach and looking at the 'lander' (boat models)
and displaying clip brushes will show that the common/clipweap brush
func_group for the corresponding lander models is 1.5 times the size of the
displayed misc_model for the lander. misc_models for the lander have a
modelscale value of 1.5.

Also, loading up mp_beach in the latest nightly doesnt display all the game
textures due to a lack of a proper shaderlist.txt file (the water texture is
missing for example). Also many many models don't display their textures
when any 'skinned' entity mode is on. Some display, but most don't -- and
i've seen this in WolfRad as well... Missing textures or a PK3 problem?

My quick list so far.
