image: add image group

Add a new view called ImageGroup that will handle all advanced image
hacks from now on.

This includes the indicator (which is now animated), any selection
indicators, and the weirdness of the album song image. All of that
is now handled by ImageGroup. This is the culmination of probably
a day and a half of wrangling with android insanity and having to
remove a lot of what I liked about the indicator in order to make
this work on a basic level.

The only major bug I am currently aware of with this is that the
indicator is bugged out on Lollipop devices due to bad vectors.
Again.

I never want to do this again. I cannot believe that adding a basic
indicator took this long and required so much stupid hacks and
inefficient code. And then google wonders why android apps are so
visually unappealing and janky and laggy. Hm. Must be that devs aren't
using the brand new FooBarBlasterFlow library!
