[TYPO3-team-core-v5] Make use of PHP 5.3 features!

[Karsten Dambekalns]

Hi.

Today I put a first batch of PHP 5.3 code into SVN, and it provides for 
some nice goodies. An example is the new constant __DIR__ which can (and 
should) be used instead of dirname(__FILE__) - it is faster!

So make sure to check your code, read about the new stuff in 5.3 and 
keep those things in mind when writing new code.

Worth reading are the slides at http://ilia.ws/talks.php
