Feature request: Export visualized output

[J-Moravec]

I would like to export and save the visualized output (trees, population graph and tables) from the PhyloWGS Witness.

I was able to export these things by saving the HTML, going through it with the inspection tools and deleting various parts, including the tree list on the right side, printing into the PDF and then parsing the individual graphs from PDF. This is not ideal for many reasons.
