lua fix yellow and add temploader

Browse source 
temp loader allows some lua requires to be loaded and
later garbage collected unfortunately the module needs to be formatted
in such a way to pass back a call table in order to keep the functions
within from being garbage collected too early

BE AWARE this bypasses the module loader which would allow code reuse
so if you aren't careful this memory saving tool could spell disaster
for free RAM if you load the same code multiple times
