Phone types not recognized in Outlook or iOS

[p-w]

The current build generates a vcard which cannot be parsed by Outlook or iOS.
This is specific to the Phone and Email-Types.

Currently it is:

TEL;WORK:+49 (0) 123 456
TEL;FAX:+49 (0) 123 456
TEL;CELL:+49 (0) 123 456

But should be:

TEL;TYPE=WORK:+49 (0) 123 456
TEL;TYPE=WORK,FAX:+49 (0) 123 456
TEL;TYPE=WORK,CELL:+49 (0) 123 456

This is specified in the RF as well: https://www.rfc-editor.org/rfc/rfc6350.html#section-6.4.1
