v0.1-poc

lua and luac tested on physical IIgs:

• lua and luac -v return correctly
• luac compiles test.lua to bytecode
• luac can list a bytecode file
• lua can execute test.lua and luac.out
• lua can be run as REPL

lua and luac are much smaller now that we're creating a LIB for each and then linking against that.
occasionally lua and/or luac will abend on the physical IIgs but seem to run fine under GG and GSPlus.

v0.0.1-lolitworks

Initial port with just enough tuning to get it to run... something.
