Add Avatar Functionality.
Adds AvatarManager, AvatarManagerImpl, AvatarStorage and different AvatarProviders including DummyAvatarProvider, NullAvatarProvider and OfflineAvatarProvider. Also adds VCardAvatarManager and VCardUpdateAvatarManager. Updates VCard Element, so that it does not return null on calling getPhoto() and thereby produce Null Pointer Exceptions. License: This patch is BSD-licensed, see Documentation/Licenses/BSD-simplified.txt for details. Test-Information: Tests are added for AvatarManagerImpl, VCardAvatarManager and VCardUpdateAvatarManager, which passes. Tests for CombinedAvatarProvider will be added soon. Change-Id: Ia6c0f82ae496427dc0cd11841487f6c53fd0fe1c
