Added deep links for widgets

- Widgets will now open the appropriate DetailView in the app when you tap on them.
  - ...except when they don't. This is still a little buggy. It works correctly when the app is already alive in the background but only works about 75% of the time when the app isn't running yet.
- Unified the loading view into a shared view used in all places requiring loading
