#1579 Copy/Cut notes function is wrong

[Jorge]

The copy function is wrong because I'm coping a note (in task 1) and I require paste it in another note (task 2) but only when I paste it, the note is not pasted and if the task 2 has another notes, this are moved.
The cut function is similar, it doesnt let paste in task 2 in fact when I paste the notes the funcion only paste a note (from the same task 2) in deep on a existing note, but the notes are not showed in task 1. I only can get the cutted notes in task 1 if I deleted the "pasted" note.
And I also cannt drag and drop the note.
