Subject: [PATCH] Fix random bug showing disabled menu items right-clicking the
 timeline

When the backup thread is running, the upgradeToWrite() needed some
extra time to lock the document to check if we can write or not in the
sprite. Now we just check the ability to write the sprite with the new
RWLock::canWriteLockFromRead() function.
