#14 Doc missing for rubis plugin

[Olivier Cailloux]

An error may happen when trying to run the rubis method:
[AWT-EventQueue-0] ERROR
org.decisiondeck.rubis.actions.SubmitProblemAction -
org.decisiondeck.rubis.integration.IntegrationPropertyException:
userNamemissing

This may be because of missing properties in file /d2/configuration/d3-rubis.properties:
serverLocation=
userName=
password=
serviceId=
methodId=

The user guide should be modified and default values should be written to this file.
