Add feature to integrate specific ODEs with integrate_odes().
Always integrate convolutions in time, independent of whether integrate_odes() is called, and in the case of NEST Simulator, are always assumed to be processed after the subthreshold dynamics but before the condition checks; hence the observed value will always be the one "just after" the instantaneous change due to the spike event.

Fixes #440.
