Make a VCS save on ctrl+s shortcut

[galin-enso]

Pull Request Description

Save a snapshot of the project directory to the VCS on ctrl+s. If the operation fails because the VCS was not initialized previously, it will try to initialize the VCS first and then save a snapshot.

Approve from my side, but someone knowing our backend should check it as well :)

So if someone wants to save a project with a particular name, that's gonna be a different operation?

Oh, this is FILE_NOT_FOUND? I need to change that so that it returns VCSNotFound.. sorry!

Do you mean the ctrl+s shortcut being used to perform for example a whole project folder save in another location (instead of storing a project snapshot to the VCS as is implemented here)? Or having named VCS snapshots, not just time-stamped commit messages?

The latter. I suppose there will be a follow up (vcs/save takes an optional name), right?

Ok, yes. If I understand correctly the first step is to implement basic snapshot/restore functionality, which can be expanded to named snapshots later.
