KeyTable doesn't support %

[Mika Tiainen]

Hi,

I am setting up dkimpy-milter and tried using % in KeyTable to have single entry used for multiple domains as documented:

If the first value consists solely of a percent sign ("%") character, it will be replaced by the apparent domain of the sender when generating a signature.

This doesn't seem to be supported. dkimpy-milter tries to match domain with %:

dkimpy-milter[30250]: self.domain: ['example.com'], self.fdomain: %, self.iequals: None

And skips signing as they don't match.

Attached patch fixes this for my simple test setup, but not sure if it is the correct way to handle this.

Seems reasonable. We'll give it a try. Thanks.
