Minor fixes (ZkTool).
A3: Added basic documentation.
A3: Improved JavaDoc regarding security setup.
1st proposal (missing security, using comoyo Base)

- mostly copy & delete from other projects
- WebServer could likely be simplified
- plan: add authentication, use it in an example resource
Added jar-with-dependencies and proper *IT execution.
Added simple authentication and authorization (not yet A3)

- TBD: Invovle A3
Fixed some Espen's comments (parent, base ver., -version)
Added version etc info to the jar for /varz etc.
Added A3 support

- TBD: Replace our filter by A3' JerseyRequestFilter
- Consider support for user (send auth. challenge if auth. missing and required)
A3 config fix: Use the right filter, enable exception mapping

- use JerseyRoleBasedAccessControlResourceFilterFactory inst. of
  RolesAllowedResourceFilterFactory
- config Jersey to find the A3's AuthenticationExceptionMapper to get
  HTTP 401/403 and authentication challenge
- moved the filter to a diff. package
