Feed owner email and name defined in config

[smsm1]

The feed owner email and name should be in the config, rather than hard coded:

@smsm1 FYI: I've uploaded a new version. Thanks for your patience. Now you can use:

author=Your Name
email=name@example.com

and than use site.author or site.email in the template.

Note, owner is an alias for author, that is, if you prefer you can write:

owner=Your name

and use site.owner in your template. Cheers.
