- Remove GL Late-initialization. GL is now set up when RocketFigure3d is constructed. This fixes a crash / hang on Java 7.

- Splash Screen must now be closed sooner. RocketFigure3d performs this task. This fixes a crash on Linux / X11.
- Check for "-Dopenrocket.3d.disable" and do no GL setup at all if this is defined. If users find GL cause OpenRocket to crash they may specify this option and use OR (Without 3d!)
