#46 Need origin information for all NOTICEs

[J. Schutz]

Current implementation in IRCConnection.handleCommand
() for NOTICE types is deficient. Most, if not all,
NOTICEs come from another user, and we will need the
origin information up the stream.

Attached is a quick and dirty fix for this that passes
the information in the same way as the onVersionNotice
() function does (ie. inserts the orgnick and origin
into the status message).

A better way to do this would be to use the origin
information in the ServerEvent class.

The patch adds a method of onNotice that has the extra
parameters.
