"Quick fix all" for fixable PowerShell issues

[pcgeek86]

In VSCode right now, you can only Quick Fix issues one at a time. It would be great if I could "quick fix all" in the following scopes:

• Current file
• Current workspace
• Current text selection

Cheers,

I think we can target this for v1.2 iteration.

VSCode has now added "quick fix all" 🎉 It should be in the latest insider build. We should see what work is involved on our side to enable this.
