Big Picture button and chromium scrollbars

Quick hack at the big picture button, unfortunately it's forced into the
controller cookie cutter for now.

Changes to the scrollbar to make it fit in with the client window a bit
more, still figuring out which CSS attributes work correctly with
chromuim
Changed Account URL colour

Account URL colour changed to match that off the original repository
More changes to scrollbar

Found a workaround for setting the width.

Works well
Scrollbar width and more image works

Scrollbar width should match width with steam windows
Still trying to sort out the tga :/
Music Crawl Settings, URL Colour

Added missing or misplaced items in Steam's settings Music tab.

Changed URL text colour to Text instead of TextEntry
Repositioned Music Database Description Settings Label

Repositioned the label from the database region to the music library
region.
It's now next to the button to scan music

Enabled caption buttons

With the release of Music Beta, probably better to have this somewhat
useable, It's not so much in theme though, which is next on the list
Made font somewhat readable

Made the song list somewhat more readable while in it's current state
