Added enum for vector tool operation mode 

2003-08-21  Simon Budig  <simon@gimp.org>

        * app/tools/tools-enums.h: Added enum for vector tool operation
        mode

        * app/tools/tools-enums.c: regenerated

        * app/tools/gimpvectoroptions.[ch]: Use new enum.
        Add "Polygonal" Option

        * app/tools/gimpvectortool.c: New Option "Polygonal" that
        places all newly generated handles at the position of their
        anchor, effectively ensuring that only polygons can be created.

        Cleaned up the editing states. It is now possible to move anchors
        in the Insert/Delete mode. Cleaned up the associated cursors.

        Fixed warning when Shift+Ctrl-Clicking on an inactive Anchor.
