/* Disambiguation lookup script, version [0.2.7b]
Originally from: http://en.wikipedia.org/wiki/User:Splarka/dabfinder.js
 
Notes:
* Uses the API using head/appendchild(script) and callback to avoid ajax.
* Alt command finds and hilights redirects with simple CSS append (class="mw-redirect").
* Per http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=37270 we are limited to 500 subtemplates
** The query-continue seems to work fine even as a generator. Built a re-query system to do this automatically.
 
Operation:
* Adds portlet button (or works with URI parameter &finddab=true)
** Makes call to MediaWiki:Disambiguationspage links, generates array of these.
*** Makes call to generator=links / prop=templates on page title.
**** Builds array of registered links that link to disambiguation pages (that contain a disambiguation template).
***** Iterates over all <a> link objects on page, matching any that link to disambiguation, and applies green border.
***** .dablink descendant links are given a dashed border, all other found links are given a solid border.
*** Repeats call with tlcontinue if more than 500 templates have been returned in previous query.
 
This is a bit messy but at the time was the easiest and most thorough way to do it I could think of.
Of course, a bot might be much more efficient, but this is handy for quick on-the-fly live checking.
 
To do:
* test it
* centralized link list in contentSub?
* test unicode support
