[PHP 5.3 compatibility] Multiple interfaces implementation

[tipyy]

I've got this error running metrics.phar on 5.3.3 (CentOs 6.5) :

PHP Fatal error:  Can't inherit abstract function Hal\Bounds\BoundsAgregateInterface::calculate() (previously declared abstract in Hal\Bounds\BoundsInterface)
...

It seems that under php 5.3.9, a class couldn't implement 2 interfaces with a same named method.

I've commented the second implementation and modified Hal/Formater/Summary classes and Hal/Command/Job/SearchBounds to make it work but I'm not sure its a good solution.

Fixed for me in wheezy64 with PHP 5.3.3

Thank's for the report
