Introduce a command in all utilities to show environment details.

Add in all Adabas utilities (and nucleus) a command "Environment" which should write a file to /tmp with a list of all environment variables and the parameter settings (like the asterisk command). I suggest to add this command to all Software AG programs (Natural, CONNX, ++). For programs running under JRE - also the Java parameters should be listed. This will ease problem isolation as programs get executed in still more automated and scripted environments. The response to the command should be "Environment details written to /tmp/envlog.dateandtime.pid"
