House work... Getting ready for pre-made world

* Stripped down world generation. We can go back to it if needed... But
with a pre-made world coming I thought it would be best. It wasn't
working anyway. Maybe recoding it would help it work.

* Cleaned code a bit.

* Changed character texture because I could. Hahaha.
Added enemies & some path-finding

+ Enemies
+ Path-finding (rudimentary at the moment)
Changes in Description

+ Added player sprite sheet; will eventually aid in
animation/directional changes of player sprite (found it on Google...
can use it for now.)

* Changed player texture.
* Changed how player is created. There are now multiple player choices,
all of which branch off of master-class Player.class.

# Spritesheet not working properly. It is loading the cell, but it is
also loading the spritesheet over the loaded cell-texture. You'll see
what I mean when you start the game.

# We also should probably add a menu.
Read Description

+ Added enemy 'line of sight' - seems to work with multiple enemies. The
method dealing with this is easily able to accept different types of
enemies (I think).

+ Added player-texture changes when moving.

* Other changes to code to make things more fluid.
More work done on AI/combat mechanics

Combat mechanics yet to work... Getting there though.
Work on map loading/Map movement, other things...

+ Map movement
+ Map loading
+ Did some work on collision; it is not working yet

* Screen movement needs to focused/centered on player
