Explicitly sandbox Lua instances (3/4) 
This allows UI scripts (saved in preferences) to access
os.* functions (non-sandboxed), while preventing other
scripts to do so.

Lua scripts that can run os commands can execute arbitrary
code on the system. While this is a nice feature, it can be
equally dangerous.
