ircfmt: Strip eats escaped colour

[A-UNDERSCORE-D]

ircfmt.Strip() internally converts \x03 to $c, and uses it while stripping out colours. This means that if you pass the string test $c of stripping, you get the result test of stripping, as the literal $c is removed from the string as a part of the strip process.

Dodgy, it shouldn't be doing that at all. Thanks for finding the issue!
