[Gneuralnetwork] Using Git repository effectively

[Aljosha Papsch]

Hi,

while preparing the patches, I noticed that the Git repo is just a depot 
for Jeans releases. This is unfortunate, because this isn't the purpose 
of Git. Git facilitates development in a team. Right now however, I 
suspect that you do the changes outside of Git, submit them in whatever 
ways and then Jean pushes a new release to the Git repo every once in a 
while.

I propose to change this behaviour. Changes should always be made in a 
checkout of the repository, changes committed and patches generated with 
"git format-patch" or "git send-email".

Best regards
Aljosha
