JobScheduler, JOE and JID Startscript read file in ./user_bin to get environment variables

The JobScheduler startscript (./bin/jobscheduler.(sh|cmd)) call the file
./bin/jobscheduler_environment_variables.(sh|cmd)
and
./user_bin/jobscheduler_environment_variables.(sh|cmd)
to get some environment variables.

The JOE startscript (./bin/jobeditor.(sh|cmd)) call the file
./bin/jobscheduler_environment_variables.(sh|cmd)
and
./user_bin/jobeditor_environment_variables.(sh|cmd)
to get some environment variables.

The JID startscript (./bin/dashboard.(sh|cmd)) call the file
./bin/jobscheduler_environment_variables.(sh|cmd)
and
./user_bin/dashboard_environment_variables.(sh|cmd)
to get some environment variables.

Calling files in ./user_bin are new.
Reason: If you change some variables in ./bin/jobscheduler_environment_variables.(sh|cmd) then it is possible that your changes get lost after a new setup.

Create a file ./user_bin/jobscheduler_environment_variables.(sh|cmd) if you want to change the environment for JobScheduler.

Create a file ./user_bin/jobeditor_environment_variables.(sh|cmd) if you want to change the environment for JOE.

Create a file ./user_bin/dashboard_environment_variables.(sh|cmd) if you want to change the environment for JID.
