Enabling cocos2d updater for SBPro.
AppDelegate's obsolete method -modalStatusWindowStartWithTitle:(NSString*)title removed.
TaskStatusWindow a bit wider now.
Status label set to truncate middle.
Cocos2dUpdater bugfix github issue #749.
Update can be cancelled now.
Update is more responsive and will show what it is doing.
Update's progress bar is indeterminate now.
Refactoring: Cocos2dUpdater+Errors category removed.
It wasn't really helping keeping the class small.
Another refactoring is needed to split the Cocos2dUpdater class into more logical parts if possible.
