Libraries inclusion

[Facyla]

As we don't really need to define a full path for inclusion, and all inclusions occur in the same directory ("php/"), i suggest that we simply remove the "CLASSES . " path prefix in front of included files in all files in php/ folder.

The overall goal is to avoid any manual configuration and allow the app to work from any folder or subfolder.

I've tested that in Crowdsourcing template and there doesn't seem to be any side-effect, so if you're ok i could deploy that to the other templates.
