lua: make it easier to disable strict mode global variables

Browse source 
After this commit, the "strict mode" lua variable errors may be
disabled with

  ilua.strict = false

and reenabled with

  ilua.strict = true

There will typically be no noticeable performance difference from
previously to this commit.

This is a bit simpler than the other methods described which
include using pcall or resetting the metatable of _G.
