Add extra functionality and final changes to the demo

[mxu24]

Issue to track progress on changes that expand on the addition of custom actions based on classes (wizard/warrior itinerary example), lua scripts (chest and gold example), and booleans (torch example) through other small additions involving similar concepts based on the current integrated examples.

Tied to pull request #1690.

We restructured the map of our demo to create a more cohesive narrative of what the Custom Scripts team has accomplished this year. The demo will dynamically load a wdl file depending on input, as well as other examples that will change depending on input. Marking this issue as closed.
