Imported some of the dynamiccore branch from love-experiments:

- Type names for love's Lua objects are specified as an argument to luax_register_type, rather than being statically defined in an array.

- luax_register_type takes a variable number of method array arguments, for registering superclass methods without copying them into the subclass' method array.

Also removed most of the header declarations for wrapper functions.
