Get build-namelist to command-line interface standard

The build-namelist interface is not updated to our new command-line interface standard and should be. Specifically it still allows long options names with a single dash, doesn't have a long name for silent, and probably should have a long name for the "-d" option. I also suggest that bundling be turned off (single digit options), and abbreviations of long names be off as well.

Doing this will actually be a good thing as a step in moving the perl based build-namelist to a python based version.
