> PlayerSound script (requires ground recognition)

This reverts commit 0003065fc9.

+ 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.

added pully functionality,
fixed black texture bug.

Added backwards walk + cleaned character animation tree
fixed UI anchors

-fixed bugs

+ Several SFX (player and impact sounds)
+ Scripts: Impact Sounds (Small Crate & Fence)

CHANGED:
+ Duplicated jump start & end animation clips to allow keyframing events (bypassing read-only clips)
+ Added additional sound functions to playerSound script

+ Script: PlayerSounds
+ Texture: Magnet Rods (Pull & Push)
+ GUI Image: Game Logo (not yet implemented in UI)
+ Unity Scene: Title Screen
+ SFX: Footsteps (sand), test beep, switch-player sound, wind ambience
+ BGM: Just Dessert (2nd Part) (This was cut from previous facebook mp3 upload)
       Purely for testing purposes.
+ Audio Source for wind ambience sounds

CHANGED:
> A duplicate of "Cycle Run" was made so that sound events can be keyframed into the
  running animation (FBX-animations were initially read-only)
> Added "PlayFootstep" sound event to running animation.
> Changed invisible wall positions near the starting point area
> Slightly lowered the first concrete platform's position near the long metal beam and small crates
> Slightly increased the height of the first fences
> Added small bits of terrain hills to create "distant cliff illusion"
> SceneController script now has connection with PlayerSound script to allow switch-player sound
> MagnetGun script (Player 1) now has connection with PlayerSound script to allow object-rotation sound
> Added an Audio Source to the Player 1 Avatar object. All player sounds are assigned to this component.

NOTE:
> Only Player 1 has some sounds. Player 2 will have sounds once Player 1 has 100% sounds.
> Cutscene management will need to be discussed. Unsure whether single-scene camera changes are possible
  and easy to implement due to script structure. Having a cutscene in a seperate scene will be demanding,
  processor-wise, but can be done.
> Still have not received updated movable object textures at this time. Way past its deadline.

KNOWN ISSUES:
- On my Gaming PC, playing the game for an extended amount of time can cause the frame rate to
  flacuate from 30 to 60fps at set intervals of approximatelly every 5sec.
- The above issue can be mitigated via restarting your PC. FPS issues could possibly be caused by junk metadata build-up.
- The above issue has also been found in week #8 playtest build.

-added music

-fixed player follow
