Subject: [PATCH] Fix 'Add to Stack' showing for technologies already in the
 stack

isAlreadyAdded was only checking the currently selected stage, so
clicking a technology from the canvas (where no stage is selected in
the panel) always showed the Add button even if the tech was already
in the stack. Now checks across all stages.
