Support generating recipes

I'd be interested in helping with this, but I'm not very familiar with how Features works under the hood. Could a maintainer point me in the right direction on where to start?

+1 to provide submodule to export as recipes

Poking around in the code a little, it seems like the logical place to start would be in the addPackageFiles() method of the FeaturesManager class. I can see some potential approaches to making these changes:

1. Overwrite the current method and assume that recipes are the way forward (probably only acceptable if this would be the basis of a new major version)
2. Put code into a submodule that would decorate the current FeaturesManager class
3. Add some kind of global configuration option to export recipes instead of standard modules
4. Add a per-feature option to export a recipe instead of a standard module

Do the maintainers (or anyone else) have a preference on the best path forward?

The module can just decorate FeaturesManager
