Something about serialization/deserialization is broken

[stiber]

We (@varndorfer and @stiber) are pretty sure that deserialized synapses don't work. In a growth continuation of one of the large growth simulations, only the endogenously active neurons appear to be spiking.

Note that in v0.9.3, which only serializes the synapse information, we are able to deserialize working synapses.

The serialization file outputs the AllEdges.destinationVertices vector as all zeros. I wrote a hack to output the destVertexIndex_ vector in AllSynapsesDeviceFuncs_d.cpp at the end of a simulation and that was also all zero. The problem may be in AllSynapsesDeviceFuncs_d.cpp and not serialization
