Keep original trait values when displaying site summary

When displaying a site summary using the store command, it seems we don't mention the original trait values. This makes it difficult to know (in discrete mode) which profile corresponds to a given trait value.

Proposal: when displaying the profile table, add trait values as row identifier. That is:

A│C│D│E│F│G│ H  │I│K│L│M│ N  │P│Q│R│ S  │ T  │V│W│Y
─┼─┼─┼─┼─┼─┼────┼─┼─┼─┼─┼────┼─┼─┼─┼────┼────┼─┼─┼─
 │ │ │ │ │ │0.02│ │ │ │ │0.91│ │ │ │0.02│0.05│ │ │
─┼─┼─┼─┼─┼─┼────┼─┼─┼─┼─┼────┼─┼─┼─┼────┼────┼─┼─┼─
 │ │ │ │ │ │    │ │ │ │ │    │ │ │ │0.22│0.78│ │ │

would become

Trait|A│C│D│E│F│G│ H  │I│K│L│M│ N  │P│Q│R│ S  │ T  │V│W│Y
─────┼─┼─┼─┼─┼─┼─┼────┼─┼─┼─┼─┼────┼─┼─┼─┼────┼────┼─┼─┼─
