Release channel support (#239)

* Release channel support

- Show SideStore in Browse if it's not from the current SideStore source
- Change SideStore source URL and source ID based on if beta and nightly are in the version string
- Use StoreApp name for InstalledApp name to allow for source-specified name to show up in My Apps

* My Apps: Fix incorrect app name on first launch

* News: fix duplicate news items from multiple SideStore release channel sources

* Trusted Sources: Add stable and beta
