Small fixes to the app to make it work on Hive Android (and probably Hive OSX)

This pull request contains three fixes, see the commit messages.

I had to unfortunately check-in the configuration file. The way you had the package set up was definitely nice, with the configuration file being generated. Unfortunately the way our app store now works is, that it expects to simply be able to zip the whole repository and have a valid hiveapp archive. To not break this (new) assumption, I checked your configuration file in for now. Maybe we'll be able to support custom-build hiveapp archives in the future again and can then change this back.

There was one $apply() call missing to make Angular update the UI after an asynchronous callback. This was probably not noticed before, as it seems that callbacks on Hive OSX end up being pretty much synchronous. That's not the case on Hive Android, so an explicit refresh is necessary.

Please review, merge and then tag as v1.0.3 . Thanks for a nice app! :-)
