The Function & Command References Update

• Synchronized output. When 2 rules finish at the same time their output was mixed before.
• Each command can now have a NextCommand which indicates a subcommand (in /execute for example). Ease of use property is added that does the recursion for you.
• Each function now has a list of referenced functions. A couple properties have been added to recursively collect all functions and their commands.
• The CheckerRule Example string properties have been replaced with List properties
• All collection properties (Namespaces in data packs and all resources within a namespace) now use a custom LookupList class. This class behaves like a dictionary, but retrieves keys from the objects themselves. This results in a mixed interface between a list and dictionary.
• Added ToString methods to resources and namespaces to make them more readable in debug view.
• Two extra output methods were added. One for displaying an invalid config message and one for displaying a general message.
