+ Particle: Objective aura
+ GUI Image: Follow-Active sprite
+ New tag: "sand" (for the terrain for recognizing sand ground***)

CHANGED:
> Few changes to PlayerSound script

NOTE***
> Still currently working on getting different-ground sound script to work.

+ Updated Character textures (requires updated character FBX with proper UV)
+ Textures: Car trailer & engine
+ Object: Car Trailer (modified their UVs for easier texturing)
+ Shader: Laser PUSH (unused for now)

CHANGES:
> Created child objects for "Laser Holder PULL" for testing two-line and multiple-line line renderer.

KNOWN ISSUES:
> Using 3 or more line renderers significantly reduces frame rate. Please don't use multiple line renderers unless
it can be optimized.
