Pre-merge
Merge branch 'develop' of https://github.com/CostelloNicho/SnakeUnity2D into develop

Conflicts:
	SnakeUnity2D/Assets/Scripts/Managers/Snake.cs
Removed the ability to turn the snake in the opposite direction. This only happened when a user changed directions twice before the snake made a movement
Fixed bug that kept speed from changing
Started abstracting components for better testability.
Refactored to maximize testability. Each component is now loosely coupled and has a testing scene where its sole functionality can be tested. Updating objects inside of their testing scenes will automatically ( with the use of prefabs ) update the main game.
Replace the timer mechanism from using a float to using a timespan and enhanced the timer UI.
