[feature-request] support hyphens for pri and qrc instead of underscores

[marco-piccolino]

I name my package repos with a reverse domain namespace and hyphens, so that they are well organised and adhere to the convention of github and similar services - would like qpm to support the same convention for the qrc and pri files for consistency and to save "brain bits".

Would it not possible to just use dots, as this is the normal form or reverse URIs?
