This is mostly an upgrade release.

We upgrade graphql-java to version 12, which allows some newer features of the spec, like using triple quotes ``` e.g. for @cypher directive statements. (fixes #110)

It also upgrades the https://github.com/neo4j-graphql/neo4j-graphql-java version to 1.0.0-M03 which adds some new features like merge mutation and mutations to add relationships. This new transpiler library is exposed at the /graphql/experimental endpoint and is meant to replace the current transpiler in the future.

Other fixes

• You can now use Long as a GraphQL type for numbers larger than 32 bit, fixes #181
• It uses projected queries when an entity contains dynamic fields, fixes #149
