v4.0.1

Minor change release

This release make one small change. The connection weight random deltas are sampled from a gaussian distribution; this changes changes the sigma of that distribution from 0.1 to 0.01. This matches the behaviour of SharpNEAT 2.x.

The intention for the SharpNEAT 4.0 release was to keep parameters such as these identical to SharpNEAT 2.x, so that the core neuroevolution algorithm is as close as possible between the two versions, despite the big architectural overhaul that was made as part of the 4.0 release.
This allows us to compare the performance/efficacy of 2.x and 4.x, to give some assurance that there isn't some bug/flaw in the new 4.0 code base that impacts performance.

Future releases can then be free to explore tuning of hyper parameters and such, once we have established that 4.x performs at least as well as 2.x.
