Set default binary-caches-parallel-connections to 25
Some benchmarking suggested this as a good value. Running $ benchmark -f ... -t 25 -- sh -c 'rm -f /nix/var/nix/binary-cache*; nix-store -r /nix/store/x5z8a2yvz8h6ccmhwrwrp9igg03575jg-nixos-15.09.git.5fd87e1M.drv --dry-run --option binary-caches-parallel-connections <N>' gave the following mean elapsed times for these values of N: N=10: 3.3541 N=20: 2.9320 N=25: 2.6690 N=30: 2.9417 N=50: 3.2021 N=100: 3.5718 N=150: 4.2079 Memory usage is also reduced (N=150 used 186 MB, N=25 only 68 MB). Closes #708.
