/* Ajax recent changes and patrolling framework, version [0.0.6a] 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 r49000

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).
