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
Please could you replace this repeated configuration and binding with a simple declarative piece of micro-framework similar to the one in https://github.com/fluid-project/videoPlayer/blob/master/js/VideoPlayer_showHide.js (see FLUID-4928 for some discussion)
