dialog, it is now a tab on the the main frame.
2) Motor filtering has been enhanced
3) Sorting in the Simulation table is now supported.
4) Chinese translations have been added.
5) 3d libraries have been updated and reportedly helps on some platforms
6) Fix to critical bug introduced by Java 1.7.0_45-b18 which effected
drag & drop in the rocket component tree.
