Stage 3 nitpicky things to fix

[patudom]

• The guidelines are autoadvancing past cho_row1 and they no longer make sense. I think we should have the student actively click on the row to move on.
• Marker dot_seq5b - should start with the measuring tool reset. It doesn't encourage making a different measurement when the old measurement is still on the galaxy.
• Marker rep_rem1 - the my galaxies table should not have a Measurement Number column.
• Marker rep_rem1 - the distances are auto filling into the table as the angular sizes are measured. We don't want those to appear until we click the tape measure button.
