LPS-43575 Allow to read the portal preferences just before reading the portal properties
LPS-43575 Get all the properties of the portal properties (without any prefix) so we can read properties that are not specific to a portlet and they are portal wide
LPS-43575 I removed the line break, because the previous one declared a new var, so I wanted to show that the setting was for that var. But the next 2 set calls do not deal with the var
