The VariableFrequenyAnalyzer should display the variables sorted by their name

[mkommend]

Currently the variables in the resulting data table are displayed in random order. If it is possible they should be sorted by their name to ensure the same colors for variables over multiple algorithm runs.

Actually, I think it would be great to sort them in order of relevance (average frequency).

Replying to gkronber:

I don't think that ordering by relevance is really useful. The reason why ordering by name is IMHO superior to ordering by relevance is that so the variable colors do not change over different runs and therefore the charts become easily comparable. If I want to know which variable is most relevant for the problem i can still look at the variable impacts.

r6981: Sorted variable frequencies by the variable name and added NaturalStringComparer.

I am still not completely happy with the display of the legend in the DataTable, because the legend items are first vertically aligned and only afterwards horizontally, but I could not find a solution to this problem ([0],[1]).

Reviewed r6981 and the NaturalStringComparer.
