+fixes #172
+added a check in SweetDreamsMain to see if the timer is <= to 0. if so close application. This resulted in the application
+closing if the exit on finish was selected because the timer is always 0 or less than if it isn't running.
+modified line in Service for when timer is decreased to stop at 0.
+
+in short. the issue was being that the timer only had two states. it was either -1 or above zero. if the timer was -1 it represented both the timer was complete
+and that a timer never existed. thus the application would not close. modified the timer to be at 0 if the timer never existed and -1 if finished. above zero
+represents still in play
