80% complete save-on-close feature
Completed "abort save on close" feature
Merge branch 'master' into saveOnClose
Final changes to implement save-on-close features
Fixed triggering confirmation messages boxes when more than one view is
open.
File->close and File->exit menu items added.  Exit uses
closeAllWindows() to ensure ViewManager::closeRequest is called on the
last open window.  Exit will close all open windows but the last one in
cases of active save operation or modified file.
