UI improvements

[oskarrough]

We can keep this issue open with small ideas here and there…

• [x] the "urls" property doesn't render <a> links
• [x] extend {{each-list}} to work for comma-separated lists
• [ ] on http://localhost:4200/releases/120096 "main artist" should be a link
• [ ] figure out what to do with master/release which both could have players
• [ ] scroll to top is needed
• [ ] make player stick to right edge and height 100%? not fixed but part of layout
• [ ] show most important community data on a release
• [ ] Include entity_type_name for companies
• [ ] Show release format info (mp3?lp? etc) and link other releases? or merge them?
• [ ] master & release https://www.discogs.com/help/doc/submission-guidelines-master-release
• [ ] move "members" above "urls" on /release/info
• [ ] format profile for all models (only artist has it for now)
