Issue #360 - scripts that require brushes that GIMP no longer installs
carve-it.scm, chrome-it.scm: apply slightly modified patch from Carol Spears which replaces hardcoding round brush names by creating a brush on the fly and setting its radius. Also fixed both scripts to not use deprecated color API which is even completely gone from master.
