[cr] RFR: 658: Webrev frame view does not have an indication of the current file

[Erik Helin]

Hi all,

please review this patch that makes the fragment (the part in the URL after the `#`) include the filename, not only the view and file number. This makes it easier in particularly the "Frames" view to see the filename of the file being changed (although browsers like Safari and Chrome nowadays hide parts of the URL by default). This also makes webrev.js more similar to the old webrev.ksh which included the filename in almost all URLs.

Testing:
- Local testing using Firefox on Linux x64

Thanks,
Erik
