Added new popup art, added audio, added text shader, completed most of end game sequence

- Added/Changed new artwork for end game sequence
- Added an Unlit/Transparent shader that allows you to adjust the alpha
values of the material. Now text can fade in an out and still have that
glow.
- Added audio for end game sequence, tada and aww.
- Completed most of the endgame sequence. All features are in, just
need pollish end sequence. (Add sound effects, maybe particles, etc.)
- Everything requested on  yesterdays completed build, "end game goal",
have been implemented in. End game runs smoothly, just as stated can be
pollished.

*** Noticed that framerate drops when user is looking left or right.
May be the high grass, not a hundred percent sure tho. Need to do
research.
