Try to improve status layout and design... not really successful...
Tons of things :

 - Fix NPE since Tatami has removed gravatar support : actually the
server itself did not provided anymore gravatar hash but the android
client still compute itself these hashes ('@ippon.fr' suffix is
hardcoded). TODO : Find a reliable way to compute gravatar hash and/or
support tatami avatar feature
 - Status layout are vastly improved. NOTE : it tries to mimic Google+
layout
 - StatusAdapter handles less responsabilities. Display statuses is now
handle by StatusViewHolder
