* Put all expanders into <div>s, which are then wrapped in <td>s. This makes for better vertical centering, especially in IE.
* Modified Wiki.js to account for expanders now having yet another parent.
* Put note tree instructions in a <tr><td> instead of in a <div>, as <div>s alone don't belong in tables.
* Added a fixed list of startup links.
* When link in list is clicked, open corresponding note editor.
* When a startup note is added/deleted, update the list.
Still much more work to do on this before it's complete.
