Added h-card microformat support

Following the guidelines on IndieWebify.Me, one of the first steps when joining IndieWeb is to create a homepage h-card which describes your profile in a simple and open format for the web.

I have added it to my profile card, which can be verified here with the following structure:

h-card:
