[Bug 9230] Get parent folder of rss/aif and not top level so we can still honor the index only build mmps pref + restore and deprecate original source root method since it was API and create a new one to use with pref behavior

source.. = src/
output.. = bin/
bin.includes = META-INF/,\
               .,\
               plugin.xml,\
               icons/,\
               lib/,\
               os/,\
               lib/JSiMa.jar
