[SAC] Gogs upgraded from 0.9.68 to 0.9.97

[Sandro Santilli]

I've upgraded Gogs from a version 0.9.68.0807
to version 0.9.97.0901

The new version includes fixes to some bugs spotted by early
users (Bjorn, your PR subject editing should work now) and
a good amount of new fetaures, including web-based file
editor UI and web-hooks on pull-request (could these be
used for example for automatically opening a trac ticket?).

Read about more changes here:
https://github.com/gogits/gogs/releases

Please let me know if you find any problem with the new version
(possibly via tickets to https://git.osgeo.org/gogs/sac/gogs-service)

Thanks, and welcome back from holidays !
