Added some functionality to vCards

The only one issue is how to be with address, emails and phone numbers, for exaple:     
<TEL><WORK/><VOICE/><NUMBER>303-308-3282</NUMBER></TEL>
<TEL><WORK/><FAX/><NUMBER/></TEL>
<TEL><WORK/><MSG/><NUMBER/></TEL>
so how we could know what is the type of TEL, work or home, and is it fax or voice.. if there any easy way to achive this please reply. Thanks for cool library!
