//***********************************************
// IceKarma's WikiLinks script for ChatZilla
// Version 1.2
//   1.2 by James Ross: fix the normal links by shunting the
//       word-hyphenator as well.
// Version 2.0
//   2.0 By Glen Mailer:
//        - Converted to new plugin API
//        - Ripped out a whole load of unused stuff
//        - Also Made to fit chatzilla coding pedantics
//   2.1 By Alphax:
//        - Added basic template linking functionality
//   2.2 By Alphax:
//        - subst: and pipes now handled correctly in templates
//   2.3 by Pathoschild:
//        - reverted to 2.2 (2.3 broke all links with non-interlanguage prefixes)
//        - fixed mailto: wikilink glitch (based on 2.3 code by Stigmj)
//   2.4 By Stigmj:
//        - added support for handling mirc-colors.
