Feature added: Rotation point center property for dynamic text fields

Now a new checkbox in the dynamictextfieldeditor is available (by default set to false for legacy) to make it possible to turn dynamic text fields around its own center.
This resolves an undesirable behaviour that occurs when the text alignment is retained

Including translation to english and german
