[TYPO3-core] RFC: Bug #7096: Consistent interface for AJAX calls in the TYPO3 Backend

[Benjamin Mack]

Hey all,

this is a SVN patch request.

Type: feature

Branches: trunk only

BT Reference: http://bugs.typo3.org/view.php?id=7096

Problem:
Whenever people wanted to have AJAX in the Backend, they had to reinvent 
the wheel (with an ajax=1 param or something like that). This is very 
problematic once we have more and more parts in the Backend that are 
AJAXified.

Solution:
A new interface as a first step into consistency for AJAX calls in the 
TYPO3 Backend. It consists of two parts. The server-side component 
(typo3/ajax.php with a TYPO3AJAX instance from 
typo3/classes/class.typo3ajax.php) and a client-side part, connected to 
the AJAX objects of the prototype framework that is extended by generic 
responders (typo3/js/common.js) to handle errors. I also rewrote the 
pagetree AJAX part to work with the new interface as a first example.

Notes:
There is a documentation part that I wrote, we can create a new document 
for this or add it to TYPO3 Core APIs, after we shaped it right :)

Yes, it's not perfect yet, that's why I need some feedback, then I will 
fix the missing parts:
* Filetree is still using old code and therefore is not working properly 
right now, will be fixed for final commit.
* Nice error outputting (with a generic notification area in the 
Backend) is still missing, but the alert() output is IMHO working for now.
