Add ability to set a custom Content Type for specific files without an extension

[iserko]

Apple's apple-app-site-association file must be served with the application/pkc7-mime content type (see: https://developer.apple.com/library/ios/documentation/Security/Reference/SharedWebCredentialsRef/), but Whitenoise is serving it with application/octet-stream, because the file has no extension and as such mimetypes determines it should provide the default octet-stream.

Would it be feasible to have some sort of file -> content type mapping which we could use whenever you would like to override the mimetypes library.

I think the easiest way to handle this is to subclass WhiteNoise and use the add_extra_headers method which is explicitly provided to cope with these kinds of edge cases. The code would look something like this (untested):

class CusomWhiteNoise(DjangoWhiteNoise):

    def add_extra_headers(self, headers, path, url):
        if url == '/apple-app-site-association':
            headers['Content-Type'] = 'application/pkcs7-mime'

Would that be an acceptable solution?

@evansd that solution works just fine thanks
