…_insert' actual search and result data

Reason:
In order to enable development of sophisticated autocomplete algorithms, they will need
to process all the data relevant to autocomplete - what was the search string and which
result was the correct one.

Example to illustrate the need:
Say we are talking about these two people of interest, who are in the address book, among others:
- person 1: Bostjan Skufca <bostjan@a2o.si>
- person 2: Bostjan SkuBIC <bostjan@otherdomain.com>

Our user is used to think about the first person by the first name, "Bostjan", as he is an old friend.
The second one is a colleague at work where people call themselves mostly by surnames, "Skubic" in this case.

Without this data provided to 'autocomplete_insert', there is no way for RC to learn that when our user
enters "bos" in the To: field he thinks about person #1 (Bostjan SkuFCA), and when he starts typing "sku"
he means person #2 (Bostjan SkuBIC).
