Note Node rendering improvements

Implementation of the following improvements to the Custom Node "Note"

• Users should be able to return to the line when editing a comment (using the CTLR-ENTER combination, for example).
• Users should be able to resize the comment even if the text on a line exceeds the width of the comment.
• When the user resizes a text field, Papyrus web will re-line the text if it is wider than the size of the element.
• When the user resizes a text field and it is not possible to line up the text, a scrollbar will be added to the element.
