Git functionality testing in Frescobaldi

[Urs Liska]

Hey people,

unfortunately Wen Xin's and my time to clean up his project after the 
GSoC has been very limited, but today I can ask you for a second round 
of testing. I'm confident that the more serious issues (i.e. crashes) 
found in the first round of testing have been fixed now, and I think 
most of the remaining open issues on the tracker 
(https://github.com/wbsoft/frescobaldi/labels/gsoc-2017-git) should not 
block that branch from being merged.

So please, anyone who is using Frescobaldi from the Git repository or 
can do so is invited to check out the rewrite-vcs branch and test the 
functionality we have. You can refer to the open (and the closed) issues 
filtered in the above link and you can of course add new issues to the 
tracker.

The functionality is far from providing a comprehensive Git workflow 
coverage, and that is of course not the goal of this initial work. So 
while it is of course OK to add "feature requests" to the issue tracker, 
the task at hand is to ensure that the functionality that has been 
implemented works well.

Best

Urs
