FirePHP Implementation

[rist]

Implement FirePHP protocol within Stubbles as own Stubbles class in this directory: /src/main/php/net/stubbles/firephp

This is the original class: http://code.google.com/p/firephp/source/browse/trunk/Libraries/FirePHPCore/lib/FirePHPCore/FirePHP.class.php

I think the class should reside in net::stubbles::service::firephp, because we should not clutter our main package with such small packages.
