Auto-refresh of settings

[jnweiger]

VisiCut should remember from which git repo the settings were loaded, and regularly check that repo for updates.

Todo: how to present the updates?
Possible three way merge betweeen a) originally loaded, b) user changed, and c) suggested update.

Or only per setting: when reviewing one specific value, visualize in what way it was changed a) by the user, b) on the repo.

Needs a merge strategy. Users changes should always override repo. A feature compare-to-repo-setting would be helpful together with a (selective) revert to repo.
