menubar, menus, tables

menubar, menus, tables

- Menubar adjusted to height of menu item text
- popip menu hover highlight moved from <a> to <li> tag,
  makes for full-width highlight
- popup menu hover to highlight bypasses <span> children by
  using mouseover instead of mouseenter
- popup menu vertical and horizontal spacing tweaks

maybe still issues with menu exit/hiding

- tables now correctly respond to changed data[] model
- much streamlined processing on changes for better performance
- still could do more, but it seems pretty smooth

- not able to reproduce any issues with color picker

Make sure to do a clean build. There were files in JavaScript that did
not get updated in my recent pull of Mungo's work.
