#233 Allow PrepAndExpectedTestCase to sort only on filtered columns instead of all columns

[Luc Feys]

In some cases it is useful (and desired) to have dbUnit not sort on all columns, but only on the filtered columns when retrieving data from the database to compare with the expected results.

Therefore I would like to propose to add a feature to DbUnit that allows toggling how the data will be sorted for comparison: on all columns or on filtered columns only.

See https://sourceforge.net/p/dbunit/bugs/430/ for more details on the reasoning behind this.

Forgot to mention, but cannot edit feature request anymore:

• Default behavior would be to sort on all columns, in order to guarantee full backwards compatibility with current approach.
