Delete the ViewSourceTabContents.

This removes all the tab contents type stuff for view source mode. The
RenderViewHostManager now automatically switches RenderViews when we turn view
source mode on or off to get the desired effect.

I also moved some instances of hardcoded schemes into chrome_constants.h, and
renamed RendererCreated/Ready/Gone to RenderViewCreated/Ready/Gone to reflect
what they actually mean.
