lua LCD (Lua Compact Debug) patch

Browse source 
LCD developed 9/2015 by Terry Ellison

 We've already discarded the ldebug module from lua
 it only makes sense to discard the debug info as well
 adds 1.5 K to the binary
 saves 8 Kb on the base state
 once scripts start getting called i've seen 10-50Kb savings but it all depends on
 what exactly you are running
