Desired Behavior

It should be possible to close the items for jobs etc. in the tree with a new node "Configuration" for each folder that contains the configurartion items.

• There will be a new node Configurations under each folder with the same symbol the main menu "Configuration" has
• All items like jobs, job chains, Process classes etc. of a folder are childs of this new node
• When clicking the arrow left from the folder name the folder will be opened and the "Configuration" node is closed
  • For compatibility there is an option in the profile. When set then
    • When clicking the arrow left from the folder name the folder will be opened and the "Configuration" node is opened too.
• When clicking the arrow left from the new configuration symbol the "Configuration" node will be opened.
• When clicking the arrow again the "Configuration" node will be closed
• When clicking the name of a folder the folder will be opened and the "Configuration" node is also open
• When the folder is empty there is no arrow left from the folder name to indicate an empty folder. 

The parent folders to an object such as a job that is currently displayed should be presented in bold letters in the tree (currently the object name only is put in bold letters in the tree.
