Export multiple stat lines in HTML

[ibboard]

Now that the API handles multiple stat-lines per unit type, we should output all of them in the HTML. The preferred initial suggestion is to have the unit name in the first column, then a second column with the unit type name, followed by the stats. Detail of how to render mixed stat types is still undecided as we currently rely on the table headers to define what the stat means.
