v1.2.0-beta.1

• restructured code base for a better "manual dependency injection" approach, node implementations are classes now, not instances
• factored effector out of core subsystems to remove dependency loops
• created knowledge and event processing threads to handle decoupling via knowledge object and event queues
• created node assembler and node container classes for building and storing node components respectively, node assembler can be configured to override subsystem classes
• knowledge handlers passed directly into node assembler now
• added "RID types of interest" field to config (defaults to orn:koi-net.node), which informs the node contact handler, automatically subscribing too and backfilling from node providers of those types
• handshake is now its own component
• created JSON schemas for all protocol objects
• better conditions for determining when no coordinator is known
• event worker flushes buffers before shutting down
• experimental CLI to install, create, and run node implementations
