Added support for a short variant of Hot1FrSceneChange,
which combines all the directional scene changes into one.
Due to the weird way the data is combined, significant
changes to the way ActionRecords are created had to be made.
Nancy3 introduced the kOpenParenthesis and
kCloseParenthesis dependency types, which allow for
more complicated dependency logic. This commit changes
the structure of the DependencyRecord type to support
parent-child relationships similar to the ones found
inside the original implementation's code. Also introduced
is the static canHaveHotspot() function in ActionRecord,
which is used to correctly implement cursor dependencies.
