Half-way through refactoring healthbar into healthbar + player/enemy HealthBar
Added LABColor.cs plugin as well as defineable colors for full/critical health in the Unity-GUI.

This enables simple traversal from one color to another one giving us nice transition from color a to color b.
Fixed background and border color not being updated live.
Almost every variable in Healthbar and its subclasses are configurable in the GUI.
Hide not configurable-style.
Added static pause/unpause functions to the State.cs
