Eclipse broken for mil-std-2045

Eclipse classpath has errors.

src/test/scala test file has package name that doesn't match the file-system name, which makes it impossible to run unit tests from eclipse. Renamed src/test/scala/com/tresys/mil-std-2045 to use underscores in mil_std_2045, so it matches the code.

All tests work, and VMF works also.
