A few changes:
1) Entities now use the more accurate variables 'x' and 'y' from Drawable, which don't get rounded off like the hitbox x and y.
   Instead, we do our calculations with the x/y vars and then set the hitbox to be the floor of those values.
2) Finished a bunch of the scripting stuff, can now write basic movement scripts, ish. Need to design some sort of level construct so I have somewhere to put all the enemies et al.!
3) Clean-up various bits of junk (unused lines, comments)
4) Very slight Animation change, nothing big or important
