added functionality to yes or no send email related to new job comment. If yes (send  email) then it goess to email writer, with cc to facility manager(s) and job-submitter.
reordered the way comments are displayed. Before, LIFO in two groups, facility and user comments. Now, all comments displayed in a single comment group, LIFO (with last recorded being first displayed). Also, if it's a facility - generated comment, this fact is explicitly displayed at the very beginning of the comment. Finally  I very slightly altered the display of the job Share tab (viewerManagerController) so as to state 'Users that can view this job' as a header to the list of viewers that can view job.
some minor fixes
Merge branch 'develop' into emailComments
