Drupal 5 (not fully converted)

Find a patch attached that does the following:
- Upgrades the settings form to drupal 5 standards (hook_settings was removed).
- Moves the menu callback for 'taxonomy/vocabulary' to the may_cache section (otherwise it will be called twice each page load!)
- Changes "List Mode" dropdown to radios (more consistent with the way taxonomy module and other drupal core modules do this)
- Modifies description in help section (kill this part if you don't like it, but I think it describes the module better)
