Meta: pass the testsuite

[pepyakin]

This will require at least these features:

• API for reading value of instance globals
• API for executing exported functions on the instance. This includes:
  • passing arguments and receiving result value in case of successful execution (Passing arguments while calling exported functions #17)
• call_indirect implementation (signature checking, checking the item isn't null, etc)
• jump tables (Implement real jump tables #16)
• proper instantiation that allows importing external functions
• a way of defining host functions that can access embedder defined state

All of the above are now implemented on master. The spec testsuite now passes!

That’s just awesome! Great job!
