Prefabs and auto texture loading

- In level 1 on tile 1,1 spawns an archer. To big now but that is the
next task on my list.
- Changing the player id from one to two spawns the red archer.
- If you change the type of prefab(archer, sword, castle, etc.) it will
load the correct texture. When all of the textures are done.
- The basic principle remains the same except Sprite might change to
something else.
