Added in the first half of the prototype level, up to the gravity switch and the beginning of the 2nd asteroid.
Added in the Second Part of the 3rd level.  The crashed Elite is at the end of the level to transition into the final stage.
Linked all three levels together. but now I need to make an appropriate spawning system.
Implemented a spawning system with spawn points and spawn triggers.  Much better than what we had before.
Tuned up the spawning system.  It should work pretty good for Levels 1 and 3 now.
Made some changes to L3.  Still need to be tested.
Added in L2Dev stuff.
Hopefully, all of the merge stuff actually worked this time.
Made fixes to the player getting stuck to the side of the wall.  Further testing required.
Fixed a bug that was caused by my previous bug fix:  sometimes jumps would stop after jumping because of the code I added in.
Added in GUI tutorial for wall climbing + modded some surfaces for sliding and slipperiness.
Added in the start of the asteroid boss battle.

Added basic asteroid spawning system, elite shield, and asteroid
reflection.
Boss Battle is now beatable, and can advance to level 3.  Also tried to balance the physics as best as possible.
Actually, there were more bugs.  Now you can take the elite down with lasers.  Asteroid collisions coming next!
Implemented asteroid collisions for the boss.
Integrated the regular level and the boss fight together.
Fixed a bug where delaying the elite final boss in the W call resulted in some strange behavior.
Made the rest of the first level playable.
Messed around with lighting and asteroid placement for the boss battle, and also made the player move faster in L3.
Added in a persistent object to keep track of deaths and time played.
