If contacts are completely identical, just delete them

[GoogleCodeExporter]

I had a bunch of completely identical contacts from trying to synchronize
two computers.  These should just be deleted automatically.

I found this dangerous because the function that tests for equality doesn't 
take into
account all fields. Moreover, the fields are hard-enconded in the extension, so 
if
they are extended by thunderbird in the future (or one was missing), you may 
remove
contacts that are not exact duplicates.

I don't know how to obtain the list of fields directly from thunderbird but 
there
should be a way. Any help appreciated.

@lopezibanez: Good thought. If the list changes, wo don't recognize it. So we 
need a
method to fetch all field names.

Could you code this feature, but make it optional?  My database has gotten bad 
enough 
that I'd be willing to take some risks with it.

A warning message listing supported fields would be appropriate.

Based on the above site, the attributes "properties" is maybe what is needed. 
It would allow to get all the properties of the card (contact) to compare them.

Great to see that the Mozilla folks have worked on the nsIAbCard interface. It 
used to be pretty limited in the past. Maybe the solution to this issue is now 
easy to implement. Any volunteers?

We would like to DONATE $200 in order to support for each ADD ON IMPROVEMENTS

$200 - 1- If contacts (identical EMAILS not only DOMAIN but identical 
emails)are completely identical, just show/delete them 

$200 - 2- Look for already existent contact when adding new (EMAIL check ALL 
address books/only email would be enough) 

$200 - 3- Add-On stops after deleting 4 entries (>1000 contacts). We have 
12,773 emails so its crucial.

$200 - 4- When showing the RESULTS - emails should be EDIT/SAVE!

What to do about two contacts who share one email? (happens to a set of leaders of a scouting for girls club, who share one email but have different mobile phones).

$200 - 3- Add-On stops after deleting 4 entries (>1000 contacts). We have 12,773 emails so its crucial.

More information on how to reproduce would be more helpful than money I guess ;) For most of us DCM doesn't stop after four contacts, so I guess the author (that isn't me) misses an idea how to reproduce.
