Force unsigned behaviour for bitfield enums

Browse Source 
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.
