[ENHANCEMENT] Scripting support for Lua

[EliteMasterEric]

Some games implementing scripted mod support may have a personal preference for Lua-based interpretation over hscript-based interpretation. Polymod already provides the capability for mods to add their own text files, but utility functions for Lua could be useful.

• [] Figure out what users would actually want from a Lua wrapper API.
• [] Figure out if it's possible to run interpret Lua efficiently in browser/HTML5 (optional).
