fixed invalid chars not being rendered as '?' but not at all
fixed a render glitch on cables probably noone would ever have noticed (slightly stretched on one face)
Adjusted package search path to search in working directory last. This is similar to the change that was made a while back to the PATH env variable. It's also like it is in standard Lua. Should mostly avoid issues like #191.
