gun sandbox

some technical explanations on why this is better than MMCZP: * gun animation happens through blender, increasing quality - no more typing CFrames by hand * animations are played in Lua through AnimationTrack instances in placefile instead of downloading from Roblox's CDN (downloading over HyperText is slow) - this comes at the cost of some performance over native impl * replication can be done ad-hoc a LOT EASIER * workspace does NOT store important game state - a single source of truth coming from the main script (root of all, also our only entry point to the program) * code consistency and version control w/ Git, updates from test places don't make it through to the master place easily * gun configuration still requires manual parts to be placed - a plugin would be ideal i don't think this will ever take over MMCZP, because i don't have a lot of motivation working with this platform, but hey, it is a sandbox for experiments.
