[TYPO3-core] RFC #9285: Remove all @ in front of file_exists() calls

[Ingo Renner]

Hi *,

this is a SVN patch request.

Type: Tweak

Bugtracker references:
http://bugs.typo3.org/view.php?id=9285

Branches: trunk

Problem:
The use of the @ character in front of functions to surpress warnings 
costs a lot of performance, and in case of file_exists() is not needed 
anymore since a bug with this function throwing warnings has been fixed 
in PHP in 2003 already.

Solution:
remove the @ characters in front of file_exists()
