RFE: Image Wizard coordinate entry, add fractional minutes option

[rgleason]

coordinate entry (provide preferences option for fractional minutes or fractional degrees) for both CoordinateSets.xml and UserCoordinateSets.xml

In the image wizard, I can only enter degrees and minutes, no fractional minutes, although the input field display decimals. I could solve the issue by typing in fractional degrees in UserCoordinateSets.xml. However, it would be more convenient to do it in the image wizard. In addition the UserCoordinates have fractional degrees, but the Wizard offers fractional minutes. Took me a couple of attempts to do the math right.

Possibly, nobody ran into that problem before, since why would anybody use fractional minutes for weather faxes? I was trying to overlay a pdf with depth soundings of one of the gates between the islands in my area.

We should provide an option for entering by degrees and fractional minutes to allow other uses.

Also " In addition the UserCoordinates have fractional degrees, but the Wizard offers fractional minutes."

The option should be available in both interfaces.
Set under preferences.
