Version 0.10

• add support for Jackson instead of GSON
• Bugfix in MapConverter (it just never worked and always threw an exception)
• JsonEngine no longer closes any reader/writer/streams passed to it. Doing so was never intended.
• internal exceptions are now chained as cause to a de/serialization exception (but still not responded to the client
  because we don't know if they contain sensitive information)
• added some missing registrations for standard from-string parsers
• parsing a path segment now throws PathArgumentParseException which responds its message with a 404 error to the
  client because such errors are not expected to contain sensitive information
• refactoring, including moving classes around to better organize packages
• more unit tests

Version 0.9

• Removed the grumpyrest-jetty-launcher subproject. This project contained only two helper classes that at best helped
  start a project with Grumpyrest, but had to be replaced later anyway to allow changes. Such code is better located
  in a demo, so I moved these two classes into the grumpyrest-demo subproject.
• added a HOWTO on overriding type converters
• split grumpyjson-gson out of grumpyjson and renamed the latter to grumpyjson-core.
  • moved the dependency on Gson to grumpyjson-gson
  • grumpyjson-core and grumpyrest are no longer depending on Gson
• renamed the base Java package to io.github.grumpystuff to match the group ID
• fix documentation, wiki sync and javadoc sync for the new GitHub namespace
