Git storage: change time encoding in directory names

Browse source 
We used to use [[yyyy-]mm-]nn-ddd-hh:mm:ss[~hex] in our git storage format
for directory that contained dives. Problem with the is that on Windows
the colon ':' is an illegal character in a filename. So libgit2 refuses to
clone such a repository on Windows.

So instead we now always write dive directories in git repositories as
[[yyyy-]mm-]nn-ddd-hh=mm=ss[~hex] which replaces the ':' with an '='.

Of course we load / parse both formats so that older formats still work.
The next time they are written all the names change which causes rather
huge commits, but that's the only way I see for cloud storage to work on
Windows.
