[Low Priority] Chaingun Insta-Fire

[Derpford]

Basically, when you fire the chaingun until it's empty, and let it go into the reload animation automatically...the next time you fire it, it'll jump straight to the Hold state instead of doing the spinup.

This strikes me as a fairly low-impact bug--in fact, before I tweaked the chaingun's firing animations, it was really useful. I just want to write it down so that people know it exists, and so I can maybe go back and fix it sometime when I feel like puzzling through some weird weapon behavior.
