Couple --release|--debug and type/packageType=development|app-store

[janpio]

We have --packageType (valid values: development, enterprise, ad-hoc, app-store) that "will determine what type of build is generated by Xcode".
And we have --release and --debug which defines the general build type.

1. Does it ever make sense to use --release with development?
2. Does it ever make sense to use --debug with anything but development?
3. Would --debug => development and --release => app-store be a sensible default here?

Re 1) Not really.
Re 2) Not really.
Re 3) Maybe. debug=development yes, release could also be ad-hoc depending on usecase.

So at least in this plugin here we could couple these together with useful defaults.

To investigate: Is it maybe a problem when we always add a packageType?
