minor changes to rna/python.

- raise an exception when python calls is_property_set(name) or is_property_hidden(name) and the property does not exist.
- added BLI_findstring_ptr(), which finds a named item in a listbase where that name is a pointer to a string.
- replaced inline for loops with calls to BLI_findstring_ptr() and IDP_GetPropertyFromGroup().
