Changed the default max growth factor for multistep methods using Nordsieck representation.
...
The previous value (10.0) was far too big and lead to numerical instability at high orders
because the last component of the Nordsieck vector, which has a low accuracy, could be
multiplied by 10^k which was ... huge.
These integrators are at least usable now!

removed lots of serialization in ODE
...
the only classes/interfaces for which serialization is really important in this package are the step interpolators. The reason for that is that the ContinuousOutputModel is explicitly serializable and contains step interpolators. This allows users to perform integration of any complex model and to save the result of the integration for all integration range by serializing a ContinuousOutputModel instance. This feature is a major one.

More Serialization changes, mostly for ode and friends.

Unfortunately, had to leave some abstract base classes as Serializable, since they had no senible default construters. But left them with meaningless UIDs, to break anyone that doesn't override it.
Of course, if anyone has a better patch, I'm happy to implement it. At this point, the serialization changes for [math] should be almost done.
