Nieuwe pagina

/* Ajax recent changes and patrolling framework, version [0.0.5a]
Originally from: http://en.wikipedia.org/wiki/User:Splarka/ajaxrecentchanges.js

Note:
* Patrol flags/links will sometimes show up where patrolling is not enabled.
** This was a bug in the API that generated patrol tokens too often.
** Fixed in http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=49000

Todo:
* Checkbox for batch patrolling

Wontdo:
* Parse comments
* Add (talk|contribs|block) links, click their name, lazy
* Localize error messages or focus on the log message 'logaction' (wrong tense, but it works fine).
