Filled region always defaults to straight lines (implement memory for last used line style)

[dbobber]

I'm sure others have requested this but the filled region tool box doesn't remember your last used line style. 

Can we make this happen?

personally I use pick line the most but I don't think it should default to that.

Also if you draw things consecutively the line draw type stays the same.

You only need to select it once when starting.
