Stormphrax 4.0.0

• new network (edgelands)
• huge SMP time management improvements
• NMP verification search
• a few other miscellaneous search improvements
• tuned (almost) everything
• the usual various tweaks and fixes

Stormphrax 4.0.0, no longer using basically no time with multiple threads. This release is a significant strength improvement, most noticeable in SMP games. Puzzle performance should also be improved somewhat, though please note that this is by no means a primary development focus.
