Corrected path validation. Removed the VI class, moved creation of blank VIs from hook_menu() to the VI form.

Added index page addition form. Improved VI addition form in general. Added Tree view for testing purposes. Removed content type selection element since it was of no use anyway.

Hook_vocabindex_info() has been renamed to hook_vocabindex(). General settings are now declared using hook_vocabindex() as well. Added preliminary block index addition form.

Removed screen shots and decreased footprint of thumbnails. Thumbnails now link to screen shots at drupal.org.

$vi is now being used to determine if node counts are enabled instead of comparing a term's node count with -1.

Removed options to disable CSS and JS files from admin page. Overriding or disabling those files should now be done using themes.
