Further corrections.
Correct the Rubik app for the recent changes to the library's Node.
Convert RubikCube to the new V&F center schema!

Move the Effects.setStretch to Meshbase.setStretch
Move the 'pre-multiply mesh before applying any effects' thing from [(Xsize of texture, Ysize of texture) x Mesh's zFactor] to Effects.setStretch(sx,sy,sz)
Making the Dialogs more consistent.
Correct the Legal notice.
Rename all the classes that are not exported to application to 'Internal'
