Posts to bulletin boards can now be added to a user's course blog (previously this was only the case for replies).

State of "Add to course blog" checkbox is preserved when user uploads attachments at secondary screen before returning to main composition screen to submit post.

Fixed a typo in &mt('Re: ').
