[issue12393] Packaging should provide support for extensible categories

@Éric: I agree that some support in setup.cfg would be good, but the problem is that you can't be 100% declarative - sometime the locations can only be determined at runtime. 

I assume you are thinking of something like:

[install_data]
categories = 
    cat1 = path1
    cat2 = path2

In my specific use case, declarative paths will not work in all scenarios - you have to use ctypes to call a Windows API (SHGetKnownFolderPath) to find the specific place to put things.

The two approaches can work together - the categories dictionary can be populated from setup.cfg where this makes sense, and of course for static paths it makes perfect sense. The Windows world is a lot more chaotic than static paths can cater for, unfortunately :-(
