Quick toLua feature request

["Eric Ries" <eries@...>]

It turns out that having the function toluaI_reg_types() named the same
across many toLua output files is causing trouble with our build process. Is
there any reason that we can't change the naming convention to something
like:

toluaI_PackageName_reg_types()

which fits a bit better with the naming convention used in the rest of the
file anyway.

Any thoughts?
