 ###ModSecurity sub-phases
 **Brief explanation:** ModSecurity supports real phases 1-4 and the 'virtual' one 5. Having intermediate virtual phases, like phase:2.2, would allow to order rules inside a real phase. This is especially useful for configurations integrating rules provided, for example, by a hoster and customs ones.   
 **Expected results:** Rules will be ordered, inside a phase, not only based on their occurence but also based on their sub-phase.

 **Example:**  
 - SecRule ... phase:2.6,id:1  
 - SecRule ... phase:2,id:2  
 - SecRule ... phase:2.3,id:3  
 Execution order: 2, 3, 1
