Merge dynamiccore2 into minor

Instead of a global type enum and bitfield, all types now have their own
love::Type static member. This means they automatically assign their ids, build
their bitsets, etc. As a bonus, it simplifies wrapper code since most functions
already know which type they're pushing to or getting from lua, so they can
directly get the static member (if it's called 'type').
