v20 Able to Toggle debug & godmode!

Added the ability to toggle debug & godMode during Play.
- Check the ReadMe for buttons involved.
GodMode currently enables you to see everything on the map, despite
Sight Radius and most likely, Line of sight after implemented, and will
enable you to not die, probably have unlimited bullets, and all so Move
through walls, water, cabbage, float, everything, Your basically Exempt
from almost all game rules, lol. Love it!
Updated the readme from what it was, it is still terrible but, u know.
Done a little bit of housekeeping, removing unused imports and
variables.
No Collision work yet, blegh.
OOH Man the best parts, RESPAWNING Enemies! hahahahaha!

Main;
- Decided to add mini comments section near the top, makes it easier to
remember what changes i made.
- Added godMode checks for render, movement, etc.
- Added a few comments to areas i think ill end up needing to do/add.
- Added the buttons for Debug/GodMode via Keyboard in the update loop.
- Decided to have the game start with debug enabled, but godmode
disabled.

BulletFactory;
- Removed unused Animations pewLR & pewUD.

CollisionSystem;
- Changes to the way it 'Sees' Enemies, so that the DEATH Animation
playes even if the enemy is dead.
- Commented out the Collision Code stuff since its terrible and wasting
resources currently.

Entity;
- Starting to get bloated with to much stuff, should break it into NPC &
Player Specific stuff i guess, or something.
- Added a canRespawn Bool! Used to detect if the unit can respawn,
basically making sure it has played its death animation before the
computer tries to spawn a new unit.
- Had to hand the players list to the Update loop, since it needs to
check if the player can see the unit respawning, we dont want that! wont
seem like an endless zombopolypse if they just respawn infront of you
right!
- fiddled with the idea of adding the destination of the entity to the
debugRenderer, but it looks a bit silly since the AI is shit at
traversing the map currently, great cuz there zombies, but terrible
cuz... you dont wana see how terrible it is, lol.

MapFactory;
- Removed unused import.

Awsome so we now have respawning Enemies!
Love how its all so coolies, ooh and the god mode, and in game debug
toggles, so good.
OOH GOSH im so bloody pleased with it, its actuly comming together.
Still very very much work to do;
Like cleaning up the code, Refactoring sections that realy realy need
it.
i allso wana stick in a FSM to handle some realy simple stuff for the
player and the enemy/ai in general.

Terrible spelling, but bloody GitHub does not have an auto correct, has
a spelling thing to show my spelling is bad but not an auto correct!
Guess i gota work on my spelling to :P

Till next time, Peace!
