Fix problematic Lua init and add user setting to keep 'os' and 'io' functions.

Browse source 
From the Lua 5.1 manual:
"The luaopen_* functions (to open libraries) cannot be called directly,
like a regular C function. They must be called through Lua,
like a Lua function."

All standard tables are now loaded with luaL_openlibs(), which includes os and io.
Because these are inherently unsafe, there is a new config setting:
<AllowDangerousScriptFunctions on="1" />
This is disabled by default.
The title screen will show a warning when the setting is on.
