wz_tooltip

After evaluating several different Tooltip methods, this one won as being the easiest to install (one file), and the easy ability to have multi-line data with linebreaks where I specify them.

The themes that come bundled with Alder are simply those used by Birch - any theme designed for Birch will work unaltered in Alder: simply replace the existing CSS file include/style.css, keeping the name the same.
