More efficient table on the Xaos tab when using xaos on a flame with a large number of xforms. --Code changes Use QTableView instead of QTableWidget for the xaos table. Add custom DoubleSpinBoxTableItemDelegate for this. Make row and column toggling functions work for QTableView and QTableWidget. Remove some dead code from Fractorium.h/cpp Miscellaneous hacks to keep it building on Linux.
