Add support for multiple configuration files

[aurelien-reeves-scalingo]

It could be nice to have the possibility to include multiple configuration files (supporting ERB templates) on the same model as the php-buildpack does with its nginx-includes configuration instruction

Is this the same issue as this one? #16

[aurelien-reeves-scalingo]

Not really.
The issue is about adding other configuration files than nginx.conf and server.conf.
#16 seems to imply it is actually already possible. If so, how?
