Title: Lasso selector

Add `LassoSelector` widget that behaves more like `RectangleSelector` and `SpanSelector` than the current `Lasso` widget.

Note: I put the demo in the "widgets" directory even though the `Lasso` demo is in "event_handling".

Also, note that this PR builds off of PR #724: *Only the last commit* in this PR adds the new widget.
