[TYPO3-core] RFC: Bug #11831: Remove reference operators for objects

[Oliver Hader]

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=11831

Branch: Trunk

Problem:
Since PHP5 objects are used as reference by default. Thus, using the
reference operator is not required anymore.

Solution:
Remove the reference operator "&" when it's used in an object context.

Notes:
There are some interface classes that I did not change, since using the
reference-free version with existing hooks might fail...
Testing this patch is a bit... impossible. So I'd say that it requires
carefully reading by at least two Core Developers.
