Open Croquet for Squeak 6.x

Restoring the original Open Croquet onto Squeak 6.x. (experimental)
For a long time, the community avaliable Open Croquet images exist only in bootstrap images for Squeak 3.8 and for Squeak 4.2. Actually, there is no any open solution to use the latest Squeak VM and Smalltalk language with Open Croquet architecure. So, that starting from the original version to OpenQwaq, anyone could load it from scratch onto the new Squeak. 
Below you could find install instructions, links and first steps in achiving this.

Copmaring to the original Open Croquet for Squeak 3.8/4.2:

* No Embeded Morphic apps (bugs)
* No Tweak (yet) 
* Original TContactPoint (find master on network) broadcaster/listener is replaced with WebSocket broadcaster/listener using WebClient (switching from UDP)
* Island snapshoting/serializing/restoring needs deep review
