* New fields channel_post and edited_channel_post for Update
refs #468
* setGameScore() changes
- Changed behaviour: messages with high scores will be update with new
high scores by default. (documentation fix)
- Use (new) disable_edit_message in setGameScore to disable the above new
behaviour.
- The edit_message parameter from setGameScore is no longer in use. For
backward compatibility, it will be taken into account for a while,
unless disable_edit_message is passed explicitly.
