Prosys OPC UA Java SDK 1.2.2

This is a new bug fix release, which also improves the performance of both the Client SDK and Server SDK with bigger amounts of data.

The Server SDK Tutorial includes a new chapter describing the custom NodeManager approach for providing data from a background system without using UaNode objects (see Chapter 11. MyBigNodeManager).
