[Andrés Ambrois]

Hello!

  Here's the new stuff on this release: 

  - Ceibal Jam: Fixed problem with sugartubeconnection import on old builds 
(needs testing)
  - Nate Ridderman: Change references to 'Whites' and 'Blacks' to 'White' and 
'Black'
  - Allow GnuGo to pick up game state at any point in time, including resuming 
from Journal
  - Mark territories at game end with pretty crosses. (Thanks Nate!)
  - Minor code cleanups.
  - Added licensing information to activity.info (GPLv2 or later)

  Special thanks to Nate Ridderman and Ties Stuij for the contributions!
