Updated 'wb_command -file-information' so that it will provide some information for unsupported CIFTI files.  If the file's name ends with '.nii' but fails to read as a VolumeFile (exception is thrown), try to read file the file with CiftiFile.  If successful, print out dimensions and dimension type information.  If not successful, rethrow the original exception.
