Git (SCM) issues in latest insiders

[eamodio]

• VSCode Version: 1.9.0-insider f67f87c
• OS Version: macOS Sierra 10.12.2

The new SCM changes seem to have lost a bunch of functionality as well as caused some bugs.

Bugs:

• The SCM icon (hopefully it is temporary) doesn't show any badge (count) until you open it.
• Can't open a file diff (from the SCM pane) with GitLens installed -- throws errors. I will take a look into this, but I mention it mainly because it could break a bunch of users until I get an update out. -- EDIT: I've pushed a new version of GitLens that fixes the issue (I was using a DocumentScheme of git it is now gitlens-git)

Missing features:

• Commit button is missing
• Many missing Git commands from the content menu (pull, push, etc)
• File diff is missing toggle back (and forth) to the file
• Staging lines -- was an AWESOME feature (would have been nice to even be more prominent)
• Commit message length notification

Thanks for updating GitLens - fixed the errors for me.

Much thanks for the summary, but it's always better to file each issue independently. 👍

Some of these are already fixed, some are dupes, others tracked here: #18615.

@joaomoreno will do next time -- just didn't want to create a ton of noise. Thanks!
