/* Special:Contributions Wildcard/CIDR lookup, version [0.1.3]
Originally from: http://en.wikipedia.org/wiki/User:Splarka/contribsrange.js
Notes:
* Uses the API (Requires http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=31312), which is faster than most CIDR contrib tools.
* Currently uses a GET json via <script src=""> to avoid ajax problems.
* Only currently works if submitted (or called by URL parameter, eg Special:Contributions/User).
** Checks namespace and date options in form.
* Uses: Submit any IP CIDR range /16 or from /24 to /32. Submit any string (at least 3 characters) with a suffixed asterisk.
** eg: [123.123.123.0/24 ] or [123.123.123.* ] or [Willy* ].
** NOTE: Currently seems broken with spaces in the search string. Possibly a fault of the API. %20,+,_ don't work
To do:
* Sortable by address? (not useful until pagination is available).
* More like normal Special:Recentchanges (hist)(diff) blah blah blah (except talk page existence for red/blue link) with BiDi characters?
* Option to refresh on page? (not really needed, but might be more handy than onload action only).
* Respect limit in user prefs? frm.limit.value ?
