issue-#81 supporting empty localAdr in CommTCP

[Josef Templ]

This issue has been raised in the community forum and it has been mentioned before by Ivan.
For the issue see http://redmine.blackboxframework.org/issues/81.
For the community board topic see http://community.blackboxframework.org/ ... ?f=16&t=99.

It is easy to resolve by mapping empty addresses to localhost (127.0.0.1).
The CommObxStreamsServer and CommObxStreamsClient example now works fine.

The docu of CommTCP already contained a hint that under certain Windows versions
empty addresses do not work. Since they do work now I have changed this part of the docu.

For the changes see http://redmine.blackboxframework.org/pr ... 8040b5ec28.

in the difference list.

There was a merge conflict with issue-#78.
It is resolved now.
