updates to my stix-2 and taxii-2 projects

[ringo <ringowathelet@gmail.com>]

just to let people know, I have updated some of my Stix-2 and Taxii-2 projects.

Updated the Stix-2 library "scalastix" to version 0.7 release on Maven Central repository.

The updates aim at STIX-2.0 compatibility.

The "scalastix" update flows on to the "StixToNeoDB" project that loads STIX-2.0 objects into a Neo4j graph database.

Also the release on Maven Central of "taxii2Lib-0.2", a Taxii-2 client library in scala.

There is also an updated _javascript_ "taxii2lib.js" for creating Taxii-2 clients in _javascript_.

Although these are work in progress,

let me know if you find them useful and working correctly.
