#79 DISABLE_PARTMSG feature

[J. R. Lenz]

This patch creates a FEATURE (DISABLE_PARTMSG). The function of this feature is to inhibit the propagation of the optional "comment" field when a user parts a channel, as this is most often used by floodnets to create havoc with their nasty mIRC colors/control codes.
