Fix @RequestMapping so that git label can contain periods

Spring MVC lops off the "extension" from request paths by default
(causing no end of other problems), but in this case making it
impossible, or unintuitive at best, to use version-like labels
in git repositories (e.g. 1.0.0). This change makes the mapping
a regex match which includes the whole path, not just the stem.

Fixes gh-94
