[TYPO3-core] RFC: #7957: Enable backend classes for xclassing

[Steffen Kamper]

Hi

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=7957

Branches: 4.2

There is the possibility to xclass the backend classes, but private 
declaration make it impossible to modify.

I changed class.clearcachemenu.php with a xclass test, for this i attached a 
unfunctional example extension (in BT), which adds a new item to the 
cachemenu

I changed other related with the same issue

vg  Steffen.
