Title: Ability Checking & Performance Improvements

- All unnecessary ```Feed.all``` and ```Screen.all``` calls were replaced by ```accessible_by``` to prevent loading too much data from the database (where needed ability rules were rewritten to non-block based)
- Check for feed read ability when accessing its submissions
- Admin now sees all feeds (even if they are empty)
