[TYPO3-core] make db_list.php usable for backend modules

[Holzinger Franz]

This is a CVS Patch request.

Type:
Feature

Branches:
HEAD


Description:
When someone wants to program a backend module he cannot use the code of db_list.php, class.db_list.inc and class.db_list_extra.inc.
This is because the $BACKPATH is not used here.

Solution:
Create a new base class for all db listings from where other backend classes can derive from. It will be controlled by a control array in the class and by control parameters to the script. So the list can also be filtered by the control variables.
It is also possible now to define another new wizard which helps to reduce the number of listed tables to the ones needed at a specific page.

There is hopefully no change in the normal behavoiur of the LIST module.

Greets, Franz
