Smooth the scrolling for the Bible View #1

Currently the initial scroll on the table view is jerky when a new cell is loaded. This is most likely due to loading the notes and their heights on-demand. Interestingly after a scroll through, it becomes smooth.

The degree of jerkiness is highly dependent on the device generation, so an iPad 3 is not as bad as an iPad 1.

Build 3584 is the initial attempt at smoothing the scrolling. iPad3 is a little smoother. iPad1 is smoother sometimes, slower when making large scrolls.

Cached cellHeights
Cached the cells themselves (this may not be the best thing to do?)
Ensured all labels had no clear background color

ATM, we're about as smooth as I can get it. Which isn't to say it is smooth - it isn't. sigh. The only way I know to improve the speed is to implement the display as a drawRect instead of using views. That'll take some work. Probably a v2 release.

As of build # 3826, implemented. Not quite perfect, but quite smooth even on older devices. We're using drawRect, so this is likely about as good as we can get.
