Make a clear distinction between programmer errors ("internal errors") and runtime errors, and allow configuring the server to let the programmer errors bubble up in development and unit testing. This saves a huge amount of time because it generates ordinary stack traces when things go wrong. And, if these errors occur in production, we'll catch them, and display **shields | internal error** which is the equivalent of a 500 error.
Instead of centralizing examples, specify them from within a service.
* Avoid duplication in service loading + refactor
* Avoid duplication in URLs, rename uri -> url in BaseService
This merges the `node-8` branch. The heavy lift was by @Daniel15 with refactoring from me and a patch by @RedSparr0w.
* New API for registering services (#963)
* Disable Node 6 tests on node-8 branch (#1423)
* BaseService: Factor out methods _regex and _namedParamsForMatch (#1425)
- Adjust test grouping
- Rename data -> queryParams, text -> message
* BaseService tests: Use Chai (#1450)
* BaseService: make serviceData and badgeData explicit and declarative (#1451)
* fix isValidStyle test (#1544)
* Run tests in Node 9, not Node 6 (#1543)
