/* Disambiguation lookup script, version [0.2.8] Originally from: https://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  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
