Added ability to adjust training max. Need to wire into sets to actually adjust lifts, and show on edit tab.
FTOSets now use the training max modifier when determining effective weight. Need to add to Edit Lifts View.
Added FTO Edit header to display "training" and "maxes" in the tableview.
Added new cell for 5/3/1 lift edit. Need to wire and set training maxes on update and load.
Training max now updates when weight is changed. Need to fiddle with view to prevent text cutoff.
Training max now rounds to 1, fits in label.
