/* Special:Contributions Wildcard/CIDR lookup, version [0.2.7]
Originally from: http://en.wikipedia.org/wiki/User:Splarka/contribsrange.js

Notes:
* Uses the API which is faster than most CIDR contrib tools.
** Needs 1.14 r42198+ for advanced continue.
* 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.
** Also utilizes &ucstart and &ucend date parameters if supplied manually (not supported in the UI atm).
*** These parameter soverride the form date options.
* 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* ].
* Now keeps searching until it finds crMax (or forever with crshowall=true URI parameter).
** Puts them in a nice collapsed div stack, like enhanced recent changes.
* /25 and /26 ranges now disabled, since they are inaccurate (50 parameter limit), please use /24 (ucuserprefix) or /27 (32 parameters)

To do:
* use ajax (let sysops/bots = 5000)?
