Updated functionality to paste lines that were cut fully on their own lines. Also when there are more selections than there were cut lines, it will iterate back through the cut lines and paste them in individually. If there's only one line selected then it should paste them all in order on newlines
Insert the correct number of newlines when a single selection is active.
Made sure to only use cutline on editors by being explicit that it must be an editor as a direct child of item-views. This resolves a bug where paste would not work on the settings page. also redefined the paste function to use the currently active editor when pasting instead of the editor that was active on initialization, which allows lines cut in one editor to be pasted in another. One last change was swapping the insertNewLineAbove and moveCursorToBeginningOfLine functions in the paste function, because this was causing funky tab issues.
