Responds to !issync, the whole magic of the bot. Basically this command will:

• Verify the requestor is logged in
• Ask ChanServ for flags/access list
• Verify requestor is +F in the channel (or bot owner)
• Tell the channel it’s syncing
• op up to look at the ban and invex lists
• Wait for all the lists to come in
• Identify any mismatches and execute them
• De-op
