Quality of life adjustments - Viscous Puddle Punch

[zirushton]

There should be an option to disable Viscous' Puddle Punch automatically latching onto enemy heroes and making it ground targeted. If I'm chasing someone and want to put a Puddle Punch on the wall to push them back towards me sometimes my crosshair will find their character model even just marginally and even though I'm pointing at the wall that means if they get in the way that the Puddle Punch knocks up the target rather than knocking them back to me in the direction I wanted to punch them.
