PDFViewer: Add TreeView to communicate rendering errors

Browse source 
Now that the rendering process communicates all errors upstream, and
PDFViewer has a way to tap into those errors as they occur, we can
visualise them more neatly.

This commit adds a TreeView that we populate with the errors stemming
from the rendering process. The TreeView has two levels: at the top sit
pages where errors can be found, and under each page we can see the
errors that have been found on that page. The TreeView sits below the
main PDF rendering.
