User Profile Image Selection

[LePips]

• Implements user profile image selection from local device.

  • Will crop the image to 1:1 aspect ratio when uploading to server. IMO, this is how profile images should be stored anyways and the web should also be performing 1:1 cropping
  • Will cause all profile image views to redraw, getting the new image
    • the image tag is now part the url and will get the new image URL

• Implements different caches for general and "branding" usage

  • User profile images and server splashscreens are in "branding" so that they can be used without a connection to the server and without being affected by other cache cleanup
  • Caches will have keys that ignore the host, which prevents duplicate images from the same server but with multiple urls
  • Closes Custom ImagePipeline/Cache for Splash Screen/User Profile Images #1052

• Other polish and more TODOs
