Since we renamed a bunch of functions for consistency (the like of gimp_image_width() to gimp_image_get_width() and others), most Scheme scripts ended up broken. This is a simple bash fix with `sed` to at least take care of these simple renaming cases. Many scripts are still broken for other reasons after our API evolution (to be continued).
