Support directory diffs

The side-by-side diff view of staged & unstaged changes is completely fantastic. I want to use it for all my git diff commands. Frequently I'm diffing against something other than HEAD, though. For example, I'd like to see the equivalent of git diff master in vscode.

I realize that you can set up vscode as a git difftool, but this forces you to view the files one-by-one, rather than en masse.

A way around this would be to support directory diffs. Then I'd be able to run git difftool --dir-diff to see all the diffs at once with vscode.

My .gitconfig looks like this:

[difftool "vscode"]
    cmd = code --wait --diff $LOCAL $REMOTE

I'm using vscode 1.1.1.

For comparison, the webdiff project does something like this to support running git webdiff instead of git diff at the command line. It works great.

Code is probably not going to implement this. I suggest implementing an extension which supports it or using a Git tool for that purpose.
