Added contextual menus to template items in list/grid view.
Removed the Templates preferences panel as right-clicking on items in the normal template list is now how you edit the list, reveal items in the Finder, etc.
User guide now displays ok (but it's still out of date).
Known issue: due to a bug in sandboxing, overwriting an existing file fails; as a workaround: give the file a new name instead.
Added Reveal All Templates menu command, which will show all the Templates folders in the Finder (including one in /Library if it exists).
Hooked up basic editing view for templates (accessed via the context menu).
Added description column to the list view (as an experiment - not sure about this).
