Make !othermetas and !tiers less spammy

To ease the rapid flooding of text in the Lobby chat, !othermetas and !tiers have been updated in the !faq fashion to only show a specific tier at once or general information unless specified otherwise.
Improve /othermetas further allowing target with spaces

Target get their spaces cropped so "balanced hackmons" and "tier shift" for for "balancedhackmons" and "tiershift".
Use toId rather than replace and toLowerString

toId achieves the same in one single line and better.
Add toId rather than toLowerCase on /tiers

Add toId rather than toLowerCase on /tiers so usres can input "over used" for instace instead of "overused". Safer and better.
