- operator strings were doing undo pushes (in fileselector text for example), this is dumb since the operators themselves handle undo. - interface code checks rna props are arrays rather then checking the array length. - disable properties window pin undoing. - sequencer refresh was calling undo, disable since this is clearnign global data not handled by undo. - added commented out code for drawing mesh vertex index/key index, useful for debugging shapekey - hook issyes.
