Further Collision Work!

So we got lotsa stuff done now!
Mapz;
- Changed map tile size from the ugly 32, to smaller 16x16 tiles.
- made relevant changes to required sections, mainly MapFactory.
- Still have the '[' & ']' Keys changing to fixed 32x32 tile sized maps,
need to fix that later.
- Current debug stage is ugly, but does the job.

Main;
- Collision with player and enemies now.
- Enemies still ignore player and needs to be fixed, but who cares for
now.
- Enemies freez (sort of) when they have been hit by a bullet.

Bullet Factory;
- Changes to the bullet itself, no longer an ugly | or -- shape, now
just a small * shape
- Added collision boxes to collide with the enemies now.
- Will need to change the assets folder to reflect the changes in bullet
shape.
- Changes to how the bullets are now fireing, only if they exist do they
render, and update.

Entities;
- Not much, there still mindless drooling zombies, haha

This is a bit of a dirty update!
Need to refactor lots of code due to the changes and mainly the
experimentation!
Will refactor things and do a much better, well detailed Commit.

Loving this!
Cant wait to now draw some little blood splats for the bullet hits, and
some hp to the zombies, draw up some death animations and omg, we got
some working demo right there beb!

Dirty, but working! >.<
- V
Minor Backup!

Relocated some rubbish assets into the Obsolete Folder.

Entity;
- Destroyed and stoped rendering once killed.

Main;
- In the main loop, To Not collide with dead Zombies/Entitys.

Maps;
- Fixed the map1/2 so it no longer crashes when loading them for
debugging.

Lalallaaa, Im home so im backing up my changes!
