`filters = list()` on object definition should be valid

[amylizzle]

/obj/spark_generator
	particles = new/particles/spark
	plane = PLANE_NOSHADOW_ABOVE
	alpha = 200

	filters = list(type="bloom", threshold="#000", size=3, offset=2, alpha=1)

is valid code and adds a bloom filter on init. OD compiles it but errors on object init.
