Subject: * Patch from Dr. Zini to add link() and backlink() to globlists. This
 allows   for some handy stuff like:   - Using links as a kind of tag;
 creating blog pages that list all pages     containing a given tag/link or
 not containing some other tag.   - Subscribing to mail notifications whenever
 a change is made to a page     that is a backlink of page foo. Ie, "Please
 notify me of changes in all     pages that link to my home page in the wiki" 
  - Locking any pages that are linked to from a particular page, so that    
 lists of locks can be exposed in the wiki.
