oriented unit by Elefant

how to use.
1. Put folder somewhere in the freeciv datapath
2. Go into the spec file and find and replace "path"
   with the path to the folder, including the folder itself.
   Also change xxx to the name of the graphic. If you change it to a default name, it will override the default graphic.
3. Go to the cimpletoon tilespec file and above 
   the cimpletoon.spec put "path/xxx.spec", where path is the same as before.
4. Now you should be good to add the unit to a ruleset.
