(svn r1030) Some toolbar icons are arranged differently:
- Landscaping buttons have to be accessed from the landscaping toolbar
- Landscaping toolbar can be opened from all other toolbars
- The order of buttons in the docks toolbar now matches the other toolbars
- Landscaping toolbar has new keyboard shortcuts
