[TYPO3-mvc] RFC #11978: Clearing the whole page cache using Tx_Extbase_Utility_Cache::clearPageCache() is "impossible"

[Felix Oertel]

Hey guys,

this is an SVN patch request.

Type:
=====
Bugfix

Bugtracker:
===========
http://forge.typo3.org/issues/11978

Branches:
=========
trunk

Problem:
========
It's not able to call Tx_Extbase_Utility_Cache::clearPageCache() without 
argument so it's not possible to clear the hole cache.

Solution:
=========
Make the method's argument optional.

regards, foertel
