Weapons can't fire a single particle

[Song]

When using the <Particles> type of shot effect, a weapon cannot fire less than 2 particles per shot. it just makes the weapon sound without firing anything. There are some legitimate reasons to use single particles rather than an image graphic or beam effect, so it'd be really handy if the game could manage them.

I've noticed this too, only workaround I found is to use a missile projectile type with a custom single-pixel image.
