Adjustments to use new version of tidepool-platform-client

bower hasn't been updated yet, that needs to happen once there is a stable version of platform-client to actually use (https://github.com/tidepool-org/platform-client/pull/13).

I also haven't actually tested the behavior yet.  I'm not feeling well, so I'm gonna call it a day, if you want to move this forward for me, feel free.  Otherwise, I'll pick it up tomorrow.
