Background changes

Added new mobile specific background (1000px) and I cropped the main
bg2 to 2000px wide (as it was discussed) and reprocessed them from
source to maintain quality. bg2 is now 104k and bg2_mobile is 53k.
Add icon sprite

Created a sprite with the full sized icons @ 100px wide (in order) and
then at 55px wide (in order) aligned vertically. The separation for the
first 4 is 100px, then it's 55px.
recsync background change.

reduce specific width of background and rename.
Changed icon sprites.
