#18 simplify author and maintainer name and email into one field each

[florianm]

As per #18 - template code from ckan's additional fields works nicely at the cost of introducing usage of pkg_dict and breaking the sequential handling of fields.

How about a more general solution?

We could have a 'display_field': false option on author_email and maintainer_email then add a custom display snippet for author and maintainer that would include the email link like this if present.

Actually there's an even simpler way. "author" gets hidden with 'display_field': false, and "author_email" gets rendered as name (if no email given), email (if no name given) or name as email link (if both given) via "display_email_name_field": "author". No template changes necessary, so that scales up nicely.

Also I'll close this PR and submit a cleaner PR shortly. Note to self, no merges before coffee.
