merged with master, 7 cukes failing. jasmine is green. need to remove rails.js helpers so things suck less

Huge commit I know, but move show and destroy routes into PostsController and PostsController#show into PublicsController

everything ported from pre-mysql mobile stuff.  things missing: search page, aspect switcher, notification badge.

Fixes #721 when creating a comment (ajax) the link to your own profile is fucked up and instead it linked to the user id

refactored comments to work like status_messages in the controller.  weird stuff was happening when using EM::next_tick; holding off on that for now.

401 -> 406 in controllers resolving http basic auth prompt on failed comment/status message creation.  fixed status message validation.

status messages and comments made by user will ajax onto the current page, and websocket everywhere else.

This reverts commit cb9fb0ad.
