Addon: Media library/view

[SpraxDev]

This is intended to organize media files stored on Apollo. You can create image galleries here, share these collections, your movies and series and everything else. It's supposed to share some features that Plex is offering, probably worse but independent from Plex and integrated into one platform - Won't be for everyone but sharing your self-hosted graduation or holiday pictures should already be a nice feature

The interface should share aspects of Apollo's main interface but very media focused and almost not file focused.

• Create image galleries
  • Group them in categories (basically directories)
  • Share them like normal directories would be shareable
• Add a directory to the media library from Apollo's file browser
  • This automatically tries to generate galleries, this is intended for a movie directory for example
  • Such automatically libraries are marked with an * but do not display any warnings about files being deleted in the file browser being removed from the media library
• Google Cast support
• Apple Air-Play support

// TODO: A lot of features and implementation details are still missing for this
