channel ownership base, part 1

Fleshing out the new channel ownership feature, along with a typo fix and small syntax updates.

A claim can now be staked with /claimchannel, a channel owner may change a trip's level using /setlevel

To do: unclaimchannel, setmotd, makeprivate, makepublic, renewclaim, garbage keeping, update mod commands to accept channelOwner and channelModerator, etc
