PSR-0 => PSR-4
Update QueryBuilderMocker.php
Added support for ORM execute() params
PHP 5.4 => PHP 5.3
Simplify logic
Simplify logic
Made execute() abstract in the parent class and leaving implementation
up to the ORM/ODM versions.

Tweaked to call $invocationMocker->with(...) directly rather than with
call_user_func_array() to mimick what Doctrine does internally.
Stupid php 5.3 array syntax... :)
