Release 1.1.0 Support for Postgres & Oracle

Thanks a lot to @inserpio for all the work and @praveenag for the review.

Update to Neo4j 3.1.4

This release adds support for Postgres and Oracle databases.

Please also see the updated documentation

It contains now also step by step instructions for setting up the source-databases with Docker, e.g. for testing.

All you have to do is to download the JDBC driver for the database and add it to the lib folder and use the correct parameters for the command line tool.

• fix neo4j-etl script for unix and windows to include database drivers from lib directory
• support for unsigned / tiny-int-fields thanks @kbsali
