Hi,

Following the merge of org-contacts-wl with org-contacts I thought it
would be nice to unify the interfaces.

The patches follow separately.

Open Problems:

* Make both accessible through `org-contacts-template-name', I see two (a half) possibilities
  1. Use a variable to specify a "name-email" function
  2. pass a variable to `org-contacts-template-name' to choose per call
  3. half: Use 2. but define functions (per backend) that call with the
     appropriate variable
