Añadido rango de "Magic source"

- Añadida función a la api "is_near_to_magic(pos, radius)" que comprueba que
	  la posición dada tenga en un radio dado al menos un bloque de Magical Cobble
	  o Magical Water.

	- La runa "Home_Stone" requiere estar cerca de una fuente de magia.

	- El altar también lo requere.
