Integrate Codizy into PHP Buildpack

Hi,

We've created a fork which integrate all the needed environment to run Codizy.
Codizy is a SAAS application built to optimize PHP/MySQL applications.

Our solution proposes 4 main features :

- Monitoring
- Analysis
- Profiling
- Optimization

Would it be possible to merge it into the official buildpack ? If Codizy is not used, the dependencies shouldn't have any effect, but add extra functionalities : basically, in addition to the Codizy specific codizy.so module, we add xhprof.so module and ioncube loader module.

Thanks and regards,
  Jocelyn Fournier
mmm yes, I can do this in the modify_php_ini() function extension.py, I'd be indeed cleaner
