Application/Event Printing, Event Tracking, Application Logic

Implemented basic printing functionality for applications and events.
Just disables the form buttons then prints it with the chosen printer.

Application approve/reject logic now in, should be fully functional.

Made some UI stuff dynamic in case of changes.

Wrote EventTracker logic. Unless some logic cleanups are done, this
should be complete. User is notified of starting, ongoing, and ending
events. Event Status is displayed in the Event tab.
