- library/xotcl/library/comm/Connection.xotcl: Provide temporary workaround for Tcl bug #3401422; the NSF/NX/XOTcl2 test suite completes now under Tcl8.6b2.
- created own directory structure xotcl under library containing doc, tests, apps, lib etc. and moved obvious content here. - adjusted regression test and old documentation system to work with new structure
