Wiktor 0bb600f0b3 Extend QR scanner to support VCard with IMPP field (#3027) ... Currently QR scanner supports only URIs. VCard specification allows embedding instant messaging protocols in the `IMPP` field [0]. This change will extract the first XMPP URI from `IMPP` field if a VCard has been scanned and process it just like if the XMPP URI was scanned directly. In case the contact is not already present in the roster this will pop up "Add contact" window. Example VCard with this URI: BEGIN:VCARD FN:Test Contact EMAIL:test@example.com IMPP:xmpp:test@example.com END:VCARD [0]: https://tools.ietf.org/html/rfc6350#section-6.4.3		2018-05-16 15:08:38 +02:00
