individual_prefix missing in latest version

[bjendres]

The widely used token individual_prefix is not working in the current release of the extension. The reason is the recent switch to APIv4 where this token is not automatically returned.

@dontub Could you please add a brief note on:

1. which versions are affected
2. how to resolve this issue in your greeting template smarty code?

[dontub]

This issue was introduced by #43 which was released in version 1.2.0 of More Greetings.

The token individual_prefix should be replaced with prefix_id:label.

This affects other tokens/fields that are APIv3 specific. If a token isn't resolved anymore, one should compare Contact.getFields action of APIv3 with APIv4.
