Episode 17: Particles Optimization

I decided not to follow this video, and still keep using vectors in the
particles because it's good practice for me.  Instead I took the time to turn
`particle` into a struct to save some cycles (the `(disassemble 'particle-*)`
functions look a lot nicer now) and made `zap%`.
