Title: Added folding and modelines for shared authoring

I added folding for the signature block along with folding options much like xml and perl syntax files. For back-compat I check for a no-opt for function block folding.

While going through this, I also noticed inconsistent tabbing so I figured I'd add modelines for shared authoring. It should match what most of the source was using, then I :retab'd (I noticed later that some header comments weren't aligned so adjusted those as well).
