Likeable has some where calls

[bemurphy]

Likeable has 2 calls to where finders. It should probably rely on the find_one/find_many procs.

Also, .all_liked_by_ids is mapping using .to_i:

def all_liked_ids_by(user)
  key = user.like_key(self.to_s.downcase)
  ids = (Likeable.redis.hkeys(key)||[]).map(&:to_i)
end

when .to_s would probably work and then allow it to support hash ids like Mongoid uses.

I might hack on this if I get time later.
