improvement: urls for tags can contain now only the tag or the id and tag

improvement: urls for category can be now id and category names (instead
of only id)

improvement: added 2 indexes (#image_tag.tag_id and #tags.url_name)

improvement: identification, register, search pages automatically set focus
on first form input

improvement: focus, nofocus css class now valid for all forms

fix: category comment is tag stripped in category_subcats.inc.php
(otherwise issues with html/scripts inside category comment)
