Process 'CharacteristicSource' in OpenQuake

[Damiano Monelli]

OpenQuake needs to be able to process 'CharacteristicSource's as defined in NRML (https://bugs.launchpad.net/openquake/+bug/1144207) and instantiate the corresponding object in oq-hazardlib.

Another patch, to add support for char. sources in logic trees: https://github.com/gem/oq-engine/pull/1097

We need also to add the capability to serialize ruptures coming from CharacteristicFaultSources when they are used for stochastic event set and ground motion field calculation. If I'm not mistaken we are able to serialize Simple, Planar and Complex Fault ruptures. However a CharacteristicFaultSource can be defined also as a collection of planar surfaces, so we need to add the capability to save in DB and serialize to XML collections of planar surfaces

@monelli:

Yes, you're right. I think we will need to make changes to both the event-based hazard and scenario hazard calculators to properly support multi-surface characteristic sources.
