[TYPO3-core] RFC: #10028: overrideWithExtension uses hardcoded urls

[Steffen Kamper]

Hi,

this is a SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=10028

Branches: trunk

Problem:
There are two wizards that you can override by extension:
* new page create wizard
* new content element wizard

Both are configured by typoscript, eg:
mod.web_list.newPageWiz.overrideWithExtension = templavoila
mod.web_list.newContentWiz.overrideWithExtension = templavoila

If you use that the url to the wizard is hardcoded in core: mod1/index.php

This is bad as
* extension who use this method have to use this directory
* you can't use modules with _DISPATCH this way

Solution:
Attached patch solves that and introduce a possibility to define this 
url by following vars:

$GLOBALS ['TYPO3_CONF_VARS']['SC_OPTIONS']['newPageWiz']['extension'] = 
'mod.php?M=web_mymoduleM1';
$GLOBALS ['TYPO3_CONF_VARS']['SC_OPTIONS']['newContentWiz']['extension'] 
= 'mod.php?M=tx_newcemod';

If the url isn't configured the old url is used to be compatible.

Additional Information:
The well known extensions "templavoila" and "dam" use this method and 
come along with own wizards. They will work after this patch because of 
the fallback.
