associate users and chats

tested associations, can do chat.u1 chat.u2 user.chats1 user.chats2
user can visit matches page (not showing their chats yet)
a user can click on a search result to expand its full profile
'matches' page shows waiting and active matches
user can 'unlike' a like they sent out

no link to other user's profile yet
internal server error template missing for find_or_create and matches
user can like and unlike users
user can block users in an active conversation

there is no unblocking
blocking should hide the chat AND the users in browse
block, find_or_create, matches, and update are returning pointless json to avoid missing template errors
liked button persistence
change user#index default to ajax call, remove haml from view
persistent liked button styling
