Add missing trailing slashes to crumb links in Diffusion
Summary:
In most cases this just makes the URIs more consistent, but it's funky/breakish for SVN repositories which are only partially tracked.
See also T3915, and IRC.
Test Plan:
- Browsed some repositories, verified URIs generated as expected, with trailing slashes for directories.
- Verified nothing goofy happened in the extremes (like double slashes on the first crumb).
