Implemented the compilation exapi funcs, and cleaned up the croctest code a bit; yay lambdas
Implemented a new compiler stdlib that's much better than the old one, and fixed a couple compiler bugs in the process.
Added a close() method to funcdefs so you can turn them into function closures (provided they have no upvalues).
Added hash.newNamespace to programmatically create namespaces like object.newClass.
