TxtSushi 0.2

I just released TxtSushi 0.2 with the following updates:

1. Improved type coercion. Some of the rules I was using before did not make sense. At some point I will write down what the rules are.
2. Added some extra functions/operators including a regex matcher. Here is the full list: SUBSTRING, UPPER, LOWER, TRIM, *, /, +, - (binary and unary), =, <> (not equal test), <, <=, >, >=, AND, OR, || (string concatination), =~ (regex matching)
