#2556: Easy switching between revisions while previewing a file in browser
------------------------------+---------------------------------------------

Component: browser | Version: 0.9.2

------------------------------+---------------------------------------------
While previewing a file in the browser it is helpful to be able to quickly
jump back and forth between revisions. Attatched is a patch to the current
/trunk/versioncontrol/web/browser.py to add links to the oldest, previous,
next, and most recent revisions to a file being previewed. I'm not
familiar with hacking the templates, so the links simply appear in the
'alternate' file downloads area.
