	)

Build/Fund an industry.

Parameters:

	tile	tile where industry is built
	flags	of operations to conduct
	p1	various bitstuffed elements p1 = (bit 0 - 15) - industry type see build_industry.h and see industry.h p1 = (bit 16 - 31) - first layout to try
	p2	seed to use for variable 8F

Returns:

index of the newly create industry, or CMD_ERROR if it failed
