GanttChart : out/-dent functionality for tree strucutred entries

Description

Goal:
--------------------------------------------------------------
The user should be able to move entries in and outside within an entry tree structure.
--------------------------------------------------------------

Current situation:
--------------------------------------------------------------
If an entry was accidently added within an entry tree structure, the entry must be deleted and consequently re-inserted.
--------------------------------------------------------------

Suggested changes:
--------------------------------------------------------------
Instead of deleting and re-inserting an accidently added entry, there should be a kind of out/-dent functionality like the list creation feature in word for example.
