Writing to online settings repository

[mgmax]

Currently, I can download settings from a git repository, but uploading changes is manual and cumbersome:

• Use a local git checkout
• pull manually
• commit and push manually

I would like to have some kind of "save" button so that on a lab with multiple PCs, the settings are copied from one PC to another. Using a shared network drive for the configuration folder is not possible because the code does not support concurrent access and any save operation overwrites the changes of another VisiCut instance.
