0.9.66

Added the ability to build from a flying drone! The "Camera Terminal" is now called the "Construction Terminal" and allows you to build from a freely flying camera. Welding behavior has been changed. It now always aligns with the crosshairs, without any strange misalignments. Fixed a bug that caused controls to lock up in photo mode during co-op gameplay. Default key bindings have been changed (this will only be noticeable to new players)
