Lua VM in go

Lua pattern match functions for Go.

LVIsFalse returns false if a given LValue is a nil or false otherwise true.

LVAsNumber tries to convert a given LValue to a number.

LVAsString returns string representation of a given LValue if the LValue is a string or number, otherwise an empty string.

LVCanConvToString returns true if a given LValue is a string or number otherwise false.

LVIsFalse returns true if a given LValue is a nil or false otherwise false.

IoLibName is the name of the io Library.

LoadLibName is here for consistency; the loading system has no namespace/library.
