RNA

* Added icon to property and enum property items. The latter is
  responsible for the large number of files changed.
* For RNA functions, added PROP_RNAPTR flag to ask for a PointerRNA
  as argument instead of a C pointer, instead of doing it implicitly
  with the AnyType type.

* Material: properly wrap diffuse/specular param variables, and
  rename some things for consistency.
* MaterialTextureSlot: added "enabled" property (ma->septex).
* Image: make animated property editable.
* Image Editor: make some things editable, notifiers, respect state.
* Context: fix issue with screen not being set as ID.
