/**
* Parse instructions for the HexChat logfile format.
*
* +------------+-------------------------------------------------------+->
* | Line | Format | Notes
* +------------+-------------------------------------------------------+->
* | Normal | <NICK> MSG | Skip empty lines.
* | Nickchange | * NICK is now known as NICK |
* | Join | * NICK (HOST) has joined CHAN |
* | Part | * NICK (HOST) has left CHAN (MSG) | Part message may be absent, or empty due to normalization.
* | Quit | * NICK has quit (MSG) | Quit message may be empty due to normalization.
* | Mode | * NICK gives channel operator status to NICK NICK | Only check for ops (channel operator status) and voices.
* | Mode | * NICK removes voice from NICK NICK | "
* | Topic | * NICK has changed the topic to: MSG | Skip empty topics.
* | Kick | * NICK has kicked NICK from CHAN (MSG) | Kick message may be empty due to normalization.
* +------------+-------------------------------------------------------+->
*
* Notes:
* - normalize_line() scrubs all lines before passing them on to parse_line().
* - The way HexChat logs actions is pretty dumb, we can spoof nearly all other line types with our actions. Even non-chat messages are logged with the same
* syntax. For this reason we won't parse for actions.
* - The order of the regular expressions below is irrelevant (current order aims for best performance).
* - The most common channel prefixes are "#&!+".
