I think this file should be called application_delegate_impl.h, since
ApplicationDelegateImpl is the lowest part of the stack that is contained here.

You could see ContentHandlerImpl as an implementation detail of
ApplicationDelegateImpl, but the reverse is not really true.

Also, more of the code in the cc file is actually implementing
ApplicationDelegateImpl than ContentHandlerImpl.

Alternately, you could just split ContentHandlerImpl out into its own file,
which will probably make sense as this all grows bigger anyway.

I've renamed the file and will split out ContentHandlerImpl as soon as it gets
bigger.
