Added a component for firing game events on Unity Start and added the ability to delay firing Unity Events when a Game Event is being listened to.

Added a class that maps Unity Input Actions to Game Events.  The shared package is now dependent on the Unity Input system package until it's permanently part of the engine.

Wrapped the game event listeners in a try/catch block so that if some listener to a GameEvent throws an exception, any other GameEventListeners will still get their functions called.

Made a new Util package for shared things with no clearly defined system with one script to begin with that quits a Unity application.

Removed a needless ToString() on a string variable that actually caused problems if the string in question was null.

Gave the int variable input the same treatment as the float one so you can delete it all back to 0 if you'd like.

Apparently events can't be fired from inherited classes, so the ScriptableVariable base class now has a protected function to fire its OnValueChanged event.

Attempting to get this project operational in a Unity Build.

Separated out the concrete UnityEvents that get used a bunch when using ScriptableVariables into separate files and added a bunch of monobehaviours to fire unity events based on variable values.

Test to see if I can get the context menus to create the scriptable objects to work with Unity's Package Manager before I put in all the work to redo all this stuff.
