Stable Alpha state.

I need to put on hold the development for a few weeks.
But  The app is now stable , and allows you to convert the NASA MOLA data into grey colored bitmap files, and to view the maps .

What you can do now :
- converting .lbl .img files from the NASA PDS repository
- viewing the maps ( grey color based elevation )
- reading the informations regarding those maps

Next step :
- fixing the bug in new map ( the file dialog appears twice ) 
- adding a 3D view
- refining the bitmap conversion . For now , there's too many black , and white , too few grey.
- implementing coordinates ( long, lat )
