Better background color for slide out view
Actual section titles
Draw custom background
Fade out TextView on slide
Optimize sliding view

Don't do unnecessary overdraw
Show title in reveal content view
Moved sliding into SlidingListView

So we don't have to notifyDataSetChanged() constantly - bad for
performance.
ViewPager layout optimizations - cache all bg pages

Trying to avoid ViewPager-based layouts as much as possible
Use HW layers for better sliding
Added clicking functionality
Tweaked the layout of the tiles

It is designed to fit perfectly on an N4 right now; at some point
we'll have to update the design so it works on anything.
