Add silly chainsaw revving swing sound

Yes, this is silly; it's a placeholder. :)

Note: oggenc wouldn't encode raw with an EOF and
and would crash so I arecord'ed into wav and
oggenc'd the wav. Worked better.
Exploring how to use sounds, scripts, etc.

I'm going to clean out some of the code in chainsaw.txt
but I don't want to lose it so I'm checking it in.

I want to get a script to call a Lua function in chainsaw.lua
Removing most stuff out of the .txt scripts

It's way too confusing right now to do anything in
the scripts. Seems way easier (and flexible) to just create
items in the script and do everything else in Lua.

The "check" sounds plays in this commit. That's a start.
Now for a looping idle sound.
Sounds plays every 2 seconds using OnTick
Plays idle sound
Chainsaw idle sound toggles on primary equip

Checks if the chainsaw is equipped before playing the chainsaw idle
sound; plays the idle sound immediately if the chainsaw gets equipped.
Set flag instead of checking item every 4 seconds.

Also removed a bunch of debug output.

Chainsaw doesn't play swing sound anymore; might need axe animation or
something?
