* fix #65 - After adding a comment it should be displayed immediately
* do this for line and commit comments
* on comment model creation use comment message from body_html or from body property (last is taken in cases the comment is returned by the creation command)
* return in all cases after comment creation the newly created comment
* use commentMessage instead of body_html which is not there in any case
* after deletion of comments remove comment from collection instead only removing it from view
* this fix reappearing comments after new comment creation
