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.
Apparently there is a new map with the index 55 -- a related entry was
added to the worldmap.txt file to prevent data loss, just in case.
<StartData ch=... /> field is not yet handled missing.
Hopefully the resulting format can be loaded on android without problems,
especially because both "ingr" and "ingrNames" fields appear in the
StartData tag now.
