• Biohazard dude uses an idle standing animation for shooting his goo gun.
• This animation has a big sideways sway in the middle, which looks weird.
• There exists an actual attack animation (ATA), but it is equally unsuited due to sway.
• This change introduces a new ATA2 animation that consists of the first 90 frames of the standing idle animation, played forwards, then backwards (pingpong)

Plan is to change more issues with this guy in this PR.
