Removed the special case to delete BodyMedia entries for a user when they first use the new version.  It's not necessary now that we're using the create or update pattern.
Fixed cosmetic problem with extra paren being added to user notifications.
Re-enabled scale update.  In the case of a hardware scale, it should behave just like the tracker: update from the stored time to the scale sync time returned by the server.  In the case where the account doesn't have hardware, it will by default update from the time of the last update to now.
Added links from main connector grid to users and connecor detail pages.  Added username to top of user page.
