FLOE-207: Added tooltips

Implemented the tooltip feature for bindDialog and updated the styles to match the latest wireframes.

http://issues.fluidproject.org/browse/FLOE-207
more idiomatic here is:
"afterOpen.updateModel": {
    changePath: "{bindDialog}.model.isTooltipOpen",
    value: true
    }
