Git migration - next iteration

[Geert Janssens]

Fellows,

After some hiatus, I am now continuing to push our git migration. I just 
pushed a patch to let the Windows build pull the gnucash-docs sources 
from git instead of svn. Works fine on my test machine, we'll see 
tomorrow if it also works on the build server.

Then there are several items to discuss left. I'll start separate mails 
for each to keep the discussions somewhat focused. Previous attempts 
resulted in large threads with several discussions mixing up.
