Added module-cross communication services

• Added Equals() and GetHashCode() methods which were previously missing in both Sound and ModuleContainer.
• Added IModule and ITuple interface for abstract class ModuleScript and the multiple Tuple types respectively.
• Added InsertNewlines() to Helper which automates placing line breaks on evenly-spaced intervals prioritizing whitespace easier.
• Added ModuleScript's Read<T>() and Write<T>() methods. This allows different assemblies to access the same data without resorting to reflection.
• Added PrintHierarchy() and PrintFullHierarchy() to PathManager, allowing you to diagnose issues related to seeing the structure of the scene, such as using GetComponentsInParent or GetComponentsInChildren.
• Changed DynamicAudio to be sealed. You can no longer derive from this class.
• Changed Helper's Unwrap to include a try-catch for SecurityExceptions.
• Changed ModuleScript's IsEditor to be static. If you are referencing IsEditor outside of a script file deriving from ModuleScript, you need to now declare the type name instead of an instance.
• Changed PathManager to throw an exception if LoadVideoClips returns an empty array of videos.
• Changed ModuleContainer's constructor exception about both KMBombModule and KMNeedyModule being null.
• Changed TPScript's generic to be TModule for clarity, as it's present throughout the whole class. If you have a generic method, you are likely able to rename it back to T since it is no longer taken.
• Removed UnityComponentNotFoundException since MissingComponentException already exists.
