Adding support for additional files to be included in a play dist zip file

[alexandre-normand]

I had a need to tweak the start script that gets generated and packaged in the play app distribution zip. Since play doesn't seem to allow for customization of that script and doesn't allow for scripts or plain files to be added to it either, I thought I'd add this feature here.

I'm currently using it to package a startup script that sets a few additional options so that those don't have to be provided at command-line during startup.

thanks, looks good to me,

Could you add your name to the contributor list in the main pom file ?

Done. Thanks!
