Change rest of AI tests to floats, reenable snowball

Try adding it to deagle too. Although the routine still doesn't consider angle, so it'll pretty much be luck. Might be a waste of time. Also fix some neglected scores from before.

Hm. Score was a bit too much, AI was doing suicidal things.

small tweak. make drowning prefer higher health hogs

Teach AI to drown with shotgun too

Start on adding drowning bonus to bat/firepunch/whip. AI still is not smart enough to change direction when firepunching to face the water, or change the angle of the bat. Also try to weight cost of switches based on how many switches were available.

Add drowning to grenade too, try some little optimisations

Fix silliness
