Naming convention for bblocks independent of register

[rob-metalinkage]

A plan is underway for building block registers to be created for different governance domains and evolution processes.

The BuildingBlocks processing tools have a register import configuration and a bblocks:// resolver that allows for bblocks to be developed in one context then migrated to a new one.

The various status semantics need to be defined/explained in accordance with this process, which needs to be established.

@dr-shorthair and @rob-metalinkage are actively working to develop this proposal, and plan to prepare appropriate draft P&P to support a robust bblock development, testing and publishing cycle.
