Improved summary for gut status

[snomos]

The present summary looks like the following:

| lang-sqi            develop  0        0 0 3 0 0 |
| lang-nso            develop  0        0 0 3 0 0 |
| =====                                           |
| Total                        1        112       |
+-------------------------------------------------+

It would be very useful to see the total for each column, to resemble something like the following:

| lang-sqi            develop  0        0 0   3 0 0 |
| lang-nso            develop  0        0 0   3 0 0 |
| =====                                             |
| Total: 112                   1        0 0 330 0 0 |
+---------------------------------------------------+

Each column should be space-padded to the leflt, so that it right-align, including the total.

Also, the status report would be much easier to read if it is alphabetically sorted, cf #91 .
