Switched from maven-assembly-plugin to maven-shade-plugin for
building FATJAR.
When running from FATJAR, class-path is ". .." to help find
log4j2.properties file.
Swagger-UI can now be served direct from inside FATJAR instead
of requiring resources in filesystem.
Default package Start now controller/Controller
block-explorer.html now served via Jetty and modified to use
relative URLs instead of absolute http://localhost:9085/... style
Improved shutdown code in controller
/admin/stop API call disabled for now
Highly permissive settings.json added
