Gerald Vogt 31abd18d4e squash all into a single commit.
Make sure to replace PRODID and VERSION instead of adding
additional ones...

Only upgrade a vcard to 3.0 if it is 2.1.
Only set REV if something has been repaired.

If multiple VERSION values are set, remove all and set only the value
of the first.
If card has been repaired change PRODID to own appinfo.
