Added Object:release. Calling it is the equivalent of removing all Lua-side references to an object and doing a full garbage collection cycle (thus deleting the object from memory if nothing else in LÖVE's code is referencing it).

Any attempt to call a method on the object after it has been released will result in an error. Object:release() returns true if it was successful, or false if not (if it has already been released previously).
