more ui api changes.

- remove functions such as operator_int(), operator_enum(), operator_string
  this mixed with keyword arguments in a way that made them hard to read.
  Instead, have operator() always return properties rather then needing an argument.

- rename prop_pointer() --> prop_object(), pointer is more a C thing.

- missed item_enumR(), rename to prop_enum()
