SimpleSignEdit

• New /signwands command to give you the sign owner view/edit wands (permission simplesignedit.wands)
• The sign owner view/edit wands can be set to not work with any instance of the item but only one with a custom name ("Set Sign Owner" and "View Sign Owner" are the names)
• If you leave a line blank on the edit screen, that line will not be updated. To clear a line, put a space on it. This is to work around the fact that you can no longer see the current contents of the sign on the sign edit screen.

When you try to edit a sign, the "editing-sign" is always blank, even if the old sign had text.
