CardDAV contacts import for AVM FRITZ!Box

This is an entirely simplified version of https://github.com/jens-maus/carddav2fb. The Vcard parser has been replaced by an extended version of https://github.com/jeroendesloovere/vcard.

Features

download from any number of CardDAV servers
selection (include/exclude) by categories or groups (e.g. iCloud)
upload of contact pictures to display them on the FRITZ!Fon (handling see below)
transfer of quick dial and vanity numbers (see wiki for handling details)
if more than nine phone numbers are included, the contact will be divided into a corresponding number of phonebook entries (any existing email addresses are assigned to the first set [there is no quantity limit!])
phone numbers are sorted by type. The order of the conversion values ('phoneTypes') determines the order in the phone book entry
the contact's UID of the CardDAV server is added to the phonebook entry (not visible in the FRITZ! Box GUI)
