Sorry, we need to keep php 5.3 BC ATM

It's a problem for non finalized libs I guess but we can't upgrade our whole infrastructure in a few days... it was planned to do the migration at the end of september... it was pretty fast, too fast !

It will be a problem for Hoa/Ruler too.

So, here's what I propose:
- We need a specific `0.14.09.17` tag for any non finalized library with `~1.0` dependencies requirements, thus we can stick on this complete tag to keep php 5.3 compatibility.
- We need a specific `0.14.09.18` tag for any non finalized library with `~2.0` dependencies requirements.
