device gets and sends coordinates on photo upload
send location to server. 'locations' are now 'places' (seems like Location may be a reserved word in javascript). if one place near user, photo is created. if multiple places, array of places is sent to user to allow for selection among them
store user id in authinfo property. send user id with photo upload. fix typo in place logic on server
open a picker with the nearby locations
send selected place to server with photo. create or update place on server. create photo with place id.
Merge pull request #4 from jackrr/locations

Looks good to me!
