- Change the example configuration file from a tree to a self-documented
reference. You can still run it in sapling, but it's pretty boring.
- Moved previous example configuration to "Example Quest", in the trees
directory.
- Show viable options in prompt.
- If a user does not select a viable option, inform them, and prompt again.

the Configuration File documentation.
