I tried to clear up the naming and comments a bit. So now there are
PROP_NOT_EDITABLE and PROP_NOT_ANIMATEABLE. If the property is not
editable it is also not animate-able. RNA_property_animateable will
check for both flags so should be usable by the animation system to
determine if it can animate a property or not.

I also added an RNA_property_animated function (instead of
PROP_EVALUATED, this really was not suitable as a flag). Not sure if we
need that in the RNA api necessarily, but it might be useful for the
user interface or python to find out if a property is being animated and
so any edits of it will be lost.
