Subject: Split up http related stuff out of the page library.

Make it an interface.
Rename page to be 'local' reflecting that it reads the website off the local disk.
Update the build script to include the go version.
Switch to gorilla/mux

Remove the convert command, since we're no longer utilizing that old
layout or have any need to convert from it.
