* Add a workspace drag surface that blocks and bubble get moved to during a workspace drag. The surface is translated using translate3d instead of svg's translate attribute so that the browser does not have to repaint the entire workspace on every mouse move. This is very similar to the block drag surface. * Address code review comments * add back hasClass_ utility removed in #748 and stop using contains since it is not supported in IE
