Postboxes: when dragging by the right end the cursor is "in the air".

[azaozz]

We can make the text a dedicated handle for dragging and the rest clickable (open/close).

Alternatively the box title (h3) can be both clickable and draggable (the click is cancelled if it's dragged) and the box should shrink to the right to avoid the "cursor in the air" look.

In any case IMHO the "clickable" area should be expanded to the whole box title. Also we should probably disable dragging of open boxes.

Patch implements the first suggestion. Has an "on hover" icon that appears after the postbox title (from the crystal project set), may use another method to show where the handle is.

I agree this is an improvement, much more intuitive as well as preventing the "in the air" cursors.
