OrderFillOrKillRequest and OrderFillRequest use different interface

[apackin]

Is there are a reason these interfaces need to be different? I think it would make more sense if we stick to either fillTakerAmount or takerTokenFillAmount for both of these interfaces

Interface OrderFillOrKillRequest
{
	fillTakerAmount: BigNumber,
	signedOrder: SignedOrder,
}
Interface OrderFillRequest
{
	signedOrder: SignedOrder,
	takerTokenFillAmount: BigNumber,
}

Yup, that's an oversight. Let's standardize around takerTokenFillAmount.
