[Feature Request] git add for lfs files seems to load endlessly

[Freymaurer]

When adding large chunks of lfs files and commiting them, ARCitect runs one git add command for a larger chunk of them. Each lfs file takes quite some time to add.

Improve this by running git add command for each file. This creates a better sense of progress and makes the method more fool proof.
