Remove shortest-column-name ordering

Browse Source 
Refs #2863
The tree importer sorts columns/column groups by how populated
they are, which is of arguable utility, but the tie-breaker
of ordering by shortest column name is completely silly.

This change removes that and, in conjunction with a stable sort
algorithm, will preserve the original order of the columns.
