Changeset e907683 for irc_commands.c

Changed account set (and other account commands) syntax. Instead of
"account set acc/key value" you now do "account acc set key value". So just
the regular set syntax with a "account acc" prefix. The slash has been a
source of confusion for long enough now.

For consistency, commands like "account on acc" should now also be
"account acc on" instead. Same for the new "channel" comand, of course.
