[refactor] spot
specs
Example: a dancing droid
[extension] controls: no longer shows empty tours in tour selector
[bugfix] extension wasnt properly binding to guide.show, and can now emit events using a this.$ delegator
[feature] disco spots, flashy spots
tour#focus: refreshing an invisible spot is more awesome now
[docs, options] spot no longer defines @withMarker, Markers extension aptly does that instead
[bugfix, extension] toggler was attempting to reset a tour when none was active
[extension] markers: made even more robust, see details

- dropped #highlight and #dehighlight, functionality is now mainstreamed
  into #show and #hide respectively
- :overlay placement snapping and scrolling can now be animated
- #remove properly cleans up everything the marker builds
