Spike Tape and Traffic Patterns

Spike Tape and Traffic Patterns are implemented in the QuickStageView
files. The QuickStage has no reference to the frames(it shouldn't), so
the lines will persist between frames.
Added Line model class for SpikeTape and Traffic Patterns.
Added UISwitches in SetPieceView and ViewView. In GridOptionsView,
moved Grid Types up.
