Can set the ‘Execute On Event’ property to define when a sequence
starts executing.
Added a ‘Start Game’ event handler.
Removed old system of specifying a start sequence on the Fungus Script.
All sequence and command components are now added to the main
FungusScript object. This change enables you to make a prefab out of
any FungusScript. FungusScript prefabs can now be edited using the
Fungus Script window. You still need to instantiate a Fungus Script
prefab in order to run it.
