Make cluster trap throw at least one trap directly to the cursor.

Title. Simply enough, make cluster trap always throw one trap directly to where you're pointing, and scatter the rest randomly.

It's very annoying to throw out 2 or 3 volleys of traps at a single target, and have none of them trigger because not one trap came close to where you were targeting. I'm cool with the general array being randomized, but one should always go to the target point.
