Minor improvement to DENAdjustableModelPanel

Entire panel shouldn't exist but DAdjustableModelPanel doesn't capture
the cursor right on OSX
Lowered SKIN.DefaultBlur amount to 2
Set proper model for AR2 ammo
Added '_baseclass_classname' fields to object instance system

Use like self._baseclass_MyBaseClass.baseFunc( self ). Solves problem
with self.Base being overriden by subclasses and becoming useless as
reference. Requires that base classes be referenced explicitly, but
better than nothing.
Switched some calls to new baseclass fields
Added revolver (357)
Fixed line endings
