containsNickname

Searches a string for a substring that isn't surrounded by characters that can be part of a nickname. This can detect a nickname in a string without getting false positives from similar nicknames.

Tries to detect nicknames enclosed in terminal formatting. As such, call this *after* having translated IRC-to-terminal such with kameloso.irccolours.mapEffects.

Uses indexOf internally with hopes of being more resilient to weird UTF-8.
