Form Filler Inner 0.0.1

Work in progress, text-example of a form-filler-inner, for those pesky forms that don't have query-string parameter pre-loads. For example, action=protect (which currently has an annoying "if( $wgRequest->wasPosted()" before checking for parameters. 

This is a bare-bones script that should be mostly deprecatable by the devs writing in proper preload routines for all form items!

If you copy this, your version may become deprecated. The in-progress version is at http://en.wikipedia.org/wiki/User:Splarka/formfiller.js (but may move to MediaWiki: namespace if it becomes popular, if so, that page will become a redirect, etc etc).

Instructions: 

* Add an onload check for the page or action that has deficient unprefillable form fields like action=protect. Eg: for Special:Movepage: if(wgCanonicalSpecialPageName=='Movepage') addOnloadHook(formFillers)
* Add the IDs of the inputs (currently supports <input> (text boxes radio and checkboxes, as well as submits if enabled), and dropdown <select> lists) to the appropriate arrays
* Profit!

If you want to be able to autosubmit by URL, add to your local monobook.js (warning: a bit insecure): var submitByJsEnabled=true;
This might be good for, say, temporarily doing a bunch of batch protects or even deletes. This trick has been used to delete thousands of images on commons and much spam on Wikia. The parameter then, if enabled, is &submitForm=IDOFSUBMITBUTTON.
