Roimanager bugs

[ehennestad]

• Trace tool prints the following in the command window and does not produce a row:

  1. Interpolation requires at least two sample points for each grid dimension.
  2. Out of range subscript.

• When adjusting size of auto detection tool, the detection area is plotted in the centre f the image, not at the mouse position

• When open in Imviewer: If the imviewer app is closed, all rows are dropped. Should add a prompt asking to save rows (if no file path is set) or save changes to rois (if file path is set)
