Commit 48a697b

- Reworked how tstl detects and rewrites `require` statements during dependency resolution. This should reduce the amount of false-positive matches of require statements: require statements in string literals or comments should no longer be detected by tstl. This means require statements in string literals or comments can survive the transpiler without causing a 'could not resolve lua sources' error or getting rewritten into nonsense.

- Now using `math.mod` for Lua 5.0 modulo operations.
