Add "draftify" to XFDcloser options

[OwenX-wiki]

Draftification is one of the most common outcomes at AfD. We currently use User:MPGuy2824/MoveToDraft.js, to automate draftification. Combining the two would eliminate the extra tedious manual step.

Thank you!

Sounds like a duplicate of wikimedia-gadgets/xfdcloser#68. I'll go ahead and close this one in favor of that one. Hope that's OK!
