Add SpriteManager and Sprite Classes

get shooting to almost work, need a bit more debugging and the arrows
will be displayed. After this i'll start displaying the rooms with the
doors starting tomorrow (hopefully)
Fixed debug function, made some loop stuff clearer in cave functions - minor fixes
Cave should be good to go, lemme know if it doesn't work

swag
Organizational path stuff

.cave files will go in Content\Caves, needs to be tested
Cave should be good, needs testing

still gotta do room!
Modify SpriteManager and GameControl

So the game can no add an arrow when you press the 'S' key, but the
arrow is not being drawn, can someone better than me at programming take
a look in the SpriteManager class at the SpawnArrow() method and then in
turn at the Draw(GameTime gameTime) method because i honestly have no
idea why it's not drawing the arrow onto the screen.
I'm gonna move on to working with Cave, Map, and GUI to display a room
when you enter the game, along with the separate doors. i won't be here
tomorrow morning, but i'll try to get something done during the 20
minutes that i'm in the waiting room.
