[Users] Sorting with a reconfigured Grid

[Daniel Kastl]

Hi Sascha,

ExtJS sorting takes three parameters if I remember well.
But these three parameters are not part of WFS standard nor they are
special Geoserver parameters (at least they were not, when I tried
more or less the same as you half a year ago).
