Fixes for LostAtNight

Fixed the logic to save Sharpness and Cloudy inputs (even when not specified by user) and reset them when loading the next task; fixed logic to save ISS image's current rotation; fixed a bug when using the "Remove Selected" button when only the XY point has been chosen; fixed restoring to default the zoom/rotation/center of ISS image and VIIRS map when loading for next task; prevent save of null or incomplete data (XY and LatLon) including translated alert messages; show the ISS nadir LATLON in an easily cut-and-paste format for use in Google Earth application or external Google Maps webpage.  All changes have been tested using latest Firefox, latest Safari, and IE 11.  Test project is available on crowdcrafing.org:  http://crowdcrafting.org/app/MMM_test_lostatnight/
