profile: load vcard and display image in call frag

This patch retrieves the vcard from the disk and displays its content
in the call fragment.
It also crops the image to a circled one. This behaviour is extracted
from the ContactPictureTask and factorized in a dedicated class

We use an external library for vCard parsing, ez-vcard licensed under
the BSD 3-Clause License. The transitive dependency freemarker is
optionnal and not necessary for us (it was causing warnings during
compilation)
