Python: support the step and precision arguments in rna_idprop_ui_create.

Support the property settings that were implemented some time ago.

As an aside, change the defaults for min and max to integers: integer
values can be implicitly cast to float, but the reverse results in an
error. Also, pointer properties don't support a default value.
