[TYPO3-core] PHP version requirement

[Steffen Ritter]

Hi Stucki,
the official requirement is 5.3.7 as this is what the Release Team
decided they will support.
We know that we have implemented an Compatibility working around the
Bugs of PHP before 5.3.7. As this Layer cannot fix all issues which
might come up and we did not want to support it the official requirement
was set to 5.3.7;

The INSTALL.txt states the following:
Since PHP below version 5.3.7 has a bug in correctly resolving type
hints being in method signatures of interfaces - which need to be
defined using a map for class aliases - we suggest to use at least PHP
5.3.7. Find more details here:
 - https://bugs.php.net/bug.php?id=54624
 - http://forge.typo3.org/issues/40653

Basically you only need 5.3.7 if the extensions you are using are not
rewritten to 6.0...

Besides that it's quite easy to use dotdeb packages as already pointed out.

regards

Steffen
