Hello all,

`trim1` and `trimboth` currently trim items from one or both tails (respectively) of an array_like input but they do so without sorting the items. It has been discussed that a function such as that does not make much sense so that behaviour is being changed. Now the items will be sorted prior to trimming.

As any other backwards incompatible change, we would like to hear if anyone has an opinion on this matter before we commit to it.
