Jiggmin

- Stamps / parts / etc. show a preview graphic of what you're about to drop under the mouse.
- Created some restrictions that prevent ship parts from overlapping with each other.
- Holding down the mouse and dragging with the eraser tool now deletes any stamps / matter / etc. along the path.
- Made the ship parts a bit fancier lookin'
- Added the ability to switch in and out of testing mode in the ship editor. (Testing mode doesn't really work at all yet.)

JV is going to be down for about half an hour tonight while I do some server maintenance.

- It is now possible to import lux from PR2 into Luna. After linking your accounts, the import will automatically happen every time you log in.
- Guild chats will (maybe?) work
- Players are no longer split up between servers.
