small changes...

- allow RNA_property_enum_items to take the totitems int pointer as NULL (spares a loop on all the enum items). this change also makes enums types with no enum array crash in some places, could support these though Id rather disallow them, generating docs is a quick way to test for this.
- open recent file operator used and enum to open the recent file without an enum array, changed to an int type.
- added space_logic.py poll functions
