error handling begins...
Merge remote-tracking branch 'remotes/origin/master' into errors
implement /profile and /api/profile; error formatting
all $http errors accounted for; notice when asset unviewable
Errors for asset, slotAsset, volumeAccess, and volume (save in routes); nicer tag list
Merge remote-tracking branch 'remotes/origin/errors'
