Breadcrumbs added

The main purpose of this release is to handle some things about making it clearer how to go back.  I have added a function to display breadcrumbs of the path through the game.

This is a pretty minor change in terms of fixing things, and currently it is feeling a little bit on the kludgey side (read duck tape and bubblegum).  I'm not sure if the problems with being unable to go back were related to something which can be handled nicely in the game or not.  But I have a little bit of work done with handling the breadcrumbs.

I am now thinking that I probably want to look to see what, if anything might be needed to get it so that the iPad issues are resolved.  I have a download which should be just the HTML, and that might work.
