v18 Party Style!

Finally Moved the player into the Entity Class, Still quite messy but
does the job for the time being.
Have the player Party Spawning now, 3 controllable characters.
NO AI for the Inactive characters yet, but you can switch between them
with the 1, 2, 3 Keys.

Main;
- Removed all un-required variables that used to contain the active
player.
- Left Original x, y as start locations, will change later.

Entity;
- Changed the name of a few variables to match the more uniform 'Entity'
as apposed to Enemies specific as i was using it previously for
bug-testing.
- Refactored parts of code to make it make a little more sense, like x
to curX, etc.

Coolies!
Need to fix the Bullets since its universal across all 3 characters,
should be quick fix.
Still have not Fixed Collision! Need to implement collision class, and
make it handle the bang-age since its all individually handled
currently. SO SILLY!

Looooovvveeeing it, coming along nicely!
OOH! just remembered I'm about to draw up some sort of 'Active' icon so
you can tell which character is the currently selected character, and
etc... see how that goes SOON!
