Activate distributed standard wells.

We introduce a new parameter --enable-distributed-wells=<true|false>
for this. During startup we check that the model either only has
standard wells or that multisegement wells are actively interpreted
as standard wells (by way of passing --enable-multisegment-wells=false
as an option).
