String related improvements:

Browse Source 
(1) Fix string.char and string.byte (argument indexing was off by one)
(2) Implement string.find
(3) Change calls to charAt, which does array bounds checking, in the
    pattern matcher with calls to luaByte, which does not.
(4) Replace use of recursion with while/continue in pattern matcher.
