INTERPOLATIONS: Add a couple of limiters.
...
Use limiter_average() which is not a limiter, just returns average of
left and right derivatives, as the default limiter for prolongation.

MESH: Redistribute data blocks after each refinement.
...
There are situations when one process can suddenly have many data
blocks refined resulting in a significant memory stress before
the new blocks are redistributed among all processes. Just
redistribute data blocks each time the block refinement is
performed to avoid such a situation.
