The DOMlib javascript library was removed. It was only used for
footnote tooltips and access key fixup.

Removing the library creates a much smaller JavaScript footprint. The
size of the compacted non-edit Javascript output was reduces from 56110
bytes down to 29296 bytes.

The footnote tooltip was completely rewritten and tested in FireFox
2.0, IE 6 and Opera 9.02. Please test other browsers as well.

The acces key fixup might beahve different now on Mac platforms.
