Arrowhead filter/effect added. Differs from Illustrator's native filter in that, among other things, the arrowhead ends at the path end rather than protrudes.
Dialog boxes redone to make them larger and more readable.
Manual updated.
Removed Reverse Path, Simplify and Smooth filters as they duplicate existing functionality.
Some improvements to user-defined Crenellate definitions; removal of user-defined roulettes (both cumbersome and useless); improvements to the Path Repetition setting in Roulettes; Straighten now has no parameters.
