Iframe panel

Convert the toolbar into an iframe based solution. The code is *much* simpler and faster in my opinion. While the diff is a bit overwhelming, here are some screenshot of the currently very spartan design:

#### Open toolbar

Things to note:

* In bar mode, The toolbar is at the bottom of the page.
* When open, the toolbar is full screen.
* The design is very much incomplete, and will certainly change.
* Summary stats in the toolbar titles are not complete
* History features are not complete.
