ECL peacman well: restore calculation of the current well rates

Browse Source 
this time without looping over the whole grid. the limited rates are
only losely coupled to be the ones used by the actual source terms, so
if the rate limiting code is changed the statistics gathering piece
must also be adapted. This is kind-of sub-optimal because it requires
some code duplication, but the alternative would be _much_ less
performant...
