Welcome back Starknights!

This update completes the attachments that will appear in the demo. The 3 new attachments, including two orbitals, bring the total to 15. On top of this there is a new challenge level to add a bit of diversity and a new synergy for the "Manipulator" class. The ability to do a quick dash with the space bar, which provides I-Frames, has also been implemented. Energy shields provided by the shielder have also been overhauled and there have been other small tweaks and fixes as well.
