Redid band cover image assets

Images need to be cropped to fit the size of the screen by by and large
the page looks better. Switched most of the images for nice high res
ones I found online. Really helps to start high res and work your way
lower or cropped.
More polishing on the bands page

  * Added icons for instagram, twitter, youtube, google plus
  * Added band logos
  * Moved band website to heading link
  * Polished up the cardboard crowns page a little more since they're
essentially a headliner.. or they should be (big money shot winners,
that'll get people to the event for sure)
  * Hid DJ pages for now since they're not going to be coming this year

  Images are a little large, we may want to crop or shrink. I'll wait
until I speak with Matt
