New Build System + Fixes

Queue Construction Time

Placing structures used to be instantaneous. While convenient, players have abused this by placing walls around other players. And since players cant break structures they don't own (to prevent griefing), they'll be trapped, unable to escape. To fix this problem, there's now a queued construction time of 5 seconds for any structures that block unit movement. This includes walls, crates, furnitures, etc. Floors and pipes, however will still have instant build since they don't really block player movement and can't be abused as easily.
