overhauled playlist page

fixes issue #7

A new playlist view UI!

It now is more in line with the ones in these following pages:
- global faves (home page)
- Your Feed
- Your favourites
- Search

It has the same 3-column grid you love from the other pages already. c:
It also now displays the playlist title at the top of it.
