zero 0.5

• Make operators configurable in the [Operators] section of config.
• Make command access level configurable in the [CommandAccess] section of config.
• Improve warp flash to be more reliable from portaling and spawning.
• Activate prox bombs immediately if it's a close bomb.
• Set velocity to zero on ship spawning so it doesn't retain velocity from brick and door warps.
• Send disconnect packet on Linux interrupt signal so the bot leaves the server immediately.
• Fix tile traversability for door-adjacent tiles. Empty tiles that are not able to be occupied when doors are closed were being considered during pathfinding before.
• Fix request ship from being set with invalid values in config.
• Fix EnterDelay of 0 causing a full ship respawn instead of just setting energy to 1 in place.
