Eliminated /set %variables, halts, /slashes, $null checks, and
replaced goto jumps with while loops. Added if # condition to
/m alias and instruction responses.

Use $2- in the /m command allows excluding more than one nick.

Removed Commands from menubar to avoid usage in non-channel
windows. Also removed the double nesting of 'Mass Commands'
title in menus.
