Added support for static arrays.
Merge pull request #75 from FeedBackDevs/staticarray

Added support for static arrays.
Fix marshalling of arrays with immutable elements (at least for most cases)
Added support for enum's.

Enums are held in Lua as strings.
No support for enum values that are not valid keys.
No support for bitfields (yet?).
Conversion function performance could be improved (linear search >_<).
