[dev] Update to turba localsql source

[Karsten Fourmont]

Hi,

I'd like to update the default turba localsql data source.
It should split the name into first and last name and the address into 
individual fields (street, city,...)

The question is: how detailed do we want this to be? The vcalendar vcard 
rfc2426 splits a name into the following fields:

- Family Name
- First (given) Name
- Additional Names,
- Honorific Prefixes
- Honorific Suffixes

with an example like this:
N:Stevenson;John;Philip,Paul;Dr.;Jr.
(please note that Philip and Paul are separated by commas as they both 
compose the additional names).

Including all these 5 fields would be the easiest thing for 
compatibility with import/export to vcard data. But I think it would 
require layout tweaks to tuba to make it look agreeable.


Similar for addresses. Here the fields are:

- post office box
- the extended address
- the street address
- the locality (e.g., city)
- the region (e.g., state or province)
- the postal code
- the country name

I think here it's possible to put all of these into Turba: once for 
private address, once for the business address.

Suggestions?

Cheers,
  Karsten
