Fixes https://github.com/KristofferC/NearestNeighbors.jl/issues/169. cc @aplavin

Looking at this code now (for the first time in many years) I am not really happy with how it looks. Ideally we should only use the functions provided by Distances.jl and not need any eval_pow and eval_diff stuff.

Anyway, this seems to be a strict improvement so let's merge.
