#872: Adjust the probability of selecting a node according to its storage
capacity

-------------------------------------+--------------------------------------
If the probability of the peer selection algorithm putting a node close to
the beginning of the list were proportional to its storage capacity, then
that would better tolerate grids with a wide range of node capacities.
With a uniform selection probability, as at present, small-capacity nodes
will be expected to receive many requests to store shares that they don't
have room for, and to download shares that they don't have.
