Pholio - finish off history view
Summary:
...bsasically add a "view mode" and play with that throughout the stack. Differences are...
- normal mode has comments; history mode does not
- normal mode has inline comments; history mode does not
- page uris are correct with respect to either mode
...and that's about it. I played around (wasted too much time) trying to make this cuter. I think just jamming this mode in here is the easiest / cleanest thing at the end. Feel free to tell me otherwise!
This largely gets even better via T3612. However, this fixes T3572.
Test Plan: played around with a mock with some history. noted correct uris on images. noted no errors in js console.
