Pause Button Implemented to 'Pause' current scene by simply pushing a new scene on the stack and popping it when player resumes. Also created two new animations to be used when player walks north and south on the map. Character animations complete (may manipulate speed still)

Left for the week: Add in another GUI element, ensure works on multiple
device sizes. Also looking into adding more animations for monster npcs
as well as maybe player actions (shooting bullet, animation on zombie
death possibly) to enhance gameplay.
