Big Build

Added:
new textures, menu scene, audioclips, scripts, texture animations

Changed gameplay so that boundaries follow ball, but not top and
bottom, ball falls into the maze now smoothly.

Scaled camera as best as posibly so there is minimal clipping.

Added new scripts such as:
Audio manager: manages all audioclips (sound effects and gameplay music)
Texture scalling: All textures in menu screen scale according to screen
dimensions
Button scaling: button size scales towards screen dimensions.
Menu scripts: Keeps track of what menu user is in (gamplay is a menu)
