Removed "ApplicationHandler" and "japplication_handler" and use MSG_launch_application instead.

Also, removed the mandatory "Host, String, String[], double, double" constructor and replaced it with the old "Host, String, String[]" mandatory constructor
for the classes (updated the examples if you need an example), since we can't know from MSG the start_time and the kill_time if we launch it from
deployment file.
