Configuration: Add -> Use
Configuration code cleanup.
NodeBase will always throw when an IO error happens.

ClusterBase will not poll IsAlive; nodes must throw to get noticed.
Parse type names with our own TypeConverter.
Minor tracing in NodeBase.
Even more config update + tests.

- ClusterBuilder returns IContainer (mainly for testing)
- Clustermanager can be used to shutdown custers
- Config buidlers can autowire services (yo dawg i heard you like IoC)
- Got rid of ISupportInitialize, config.xml -> property updates are done automatically
