Ship manager update
Ship manager has been updated. Now you able to build and destroy ships, and sort tables by any column. Building and destroying have no visual effects, and no economic purposes. Constructed ship just appears in front of the camera. List of ships to build is generated form "ship scheme" scripts, located in the models/spacecrafts folder. Now installing a new addon is quite simple: just copy new files into SE folder, and new ship become available in the build menu.
