Extend .uno:OpenHyperlinkOnCursor to open all hyperlinks
in a cell, when not in edit mode.
The UNO command can be assigned to a keyboard shortcut from
`Tools > Customize > Keyboard`. If the active cell is not in
edit mode, then pressing the shortcut opens all the hyperlinks
in the cell. If in edit mode, pressing the shortcut opens the
hyperlink under the caret "|".
