Expose lua_sethook through LuaNatives

[tristantarrant]

Is your feature request related to a problem? Please describe.
I would like to register a hook to be able to implement some debug/kill functionality. I see that the various LuaXXNatives.java files exclude this call, and I may miss some background info as to why that was done.

Describe the solution you'd like
A Java class to hold lua_Debug data, and a functional JDebugHook interface with a __int hook(Lua L, LuaDebug D) method.

Describe alternatives you've considered
N/A
