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.

at integration start and is responsible for all time advancing stuff, including
step handlers and events handlers management.

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.
