NAME: SpecialMakePage
PURPOSE: Special page for creating a new page from a form

Other extensions can do this, but they don't make it at all easy to base the title on variables which are substituted from fields on the form. 

AUTHOR: Woozle Staddon
VERSION:

2007-11-23 (Wzl) Writing started 2007-11-24 (Wzl) More or less working; doesn't work with _POST data, and I don't understand why not. 2007-11-29 (Wzl) Adding variable for defining new title name 2008-01-22 (Wzl) Put in some friendly debugging text for when title can't be created 2008-06-25 (Wzl) Added "!TIMESTAMP" internal variable, and framework for adding more internal variables Future: If it ever turns out that we really want to be able to base these on the contents of a page, I suggest a syntax like <<@page_name>>. The page would need to be parsed in some cases but possibly not in others; perhaps <<@@page_name>> to indicate the page should be parsed? 2008-07-24 (Wzl) Minor tweak so it will work with MW v1.12 2008-09-29 (Wzl) - 0.4 - Made keys case-insensitive so it would work again. Don't know why this is suddenly a problem. 2009-02-11 (Wzl) clsStringTemplate is now in a separate php file 2009-02-13 (Wzl) $wgOptCP_SubstFinish "]" -> "$]" so links and other bracketed stuff don't confuse the var parser 2009-02-26 (Wzl) - 0.5 - "$objNewEdit->action = 'submit';" before "->showEditForm()" fixes MW 1.14 problem
