Some compilers (notably MSVC) were using signed values for bitfield enums. This was causing problems where 2 bits were used to store 4 or less enum values, where they were being treated as negative numbers.
This PR explicitly requests these enums to be treated as unsigned values.
Exposes the "interpolated" flag on nodes via a property, physics_interpolation_mode.
Mode can be INHERIT, OFF and ON. This makes it easy to turn off interpolation for nodes in the editor, versus via code. - lawnjelly
