input validation error..

  Improves consistency.

  (Modified the form a bit.)

- Patch #31014 by chx, zack: on taxonomy overview pages, make term names link to their respective taxonomy/term/(x) page.

  to validate other form submissions, not just comments. Two new functions
  are introduced, form_token() and form_validate(). The first function uses
  a private key and a public key to set a token in a hidden field. The second
  function validates the token. The comment and contect module are updated to
  use these functions.

* adds a "feed settings" section to admin/settings where 2 new settings are introduced:
* number of items per feed
* default length of feed descriptions (title only, teaser, full)
* patches all of core to obey the above - including the new aggregator (out) feeds
* adds support for adding namespaces in _nodeapi('rss item') - which means things like iTunes RSS and yahoo's media rss can be implemented by the appropriate modules (i.e. audio.module)
* includes some additional info in the default node feed - specifically the element (links directly to comments) - and dc:creator - to show node author information.

- Patch #29030 by Goba, chx, Jose, et al: reworked the URL rewrite hook so URLs can be rewritten dynamically.

  chx: it can be "form API"-ied now. :)

  solution until we have a better permission page.
