lodchart: get rid of plotAll; add pointsAtMarkers option

 - things were getting bogged down in iplotMScanone with plotAll
 - In iplotMScanone, don't need to points at the markers
iplotMScanone_noeff: plot LOD curves when needed

 - rather than plot all LOD curves and then selecting the relevant ones, just plot when needed
 - this gives better performance

 - I also rotated the panel on the right
