Bug 991742 part 7. Remove the "aScope" argument of WrapNode() methods. r=bholley This patch was generated with the following command: find . -name "*.h" -o -name "*.cpp" | xargs sed -e '/WrapNode(JSContext/ {; N; s/\(WrapNode(JSContext *\* *a\{0,1\}[Cc]x\),\n\{0,1\} *JS::Handle<JSObject\*> a\{0,1\}[sS]cope/\1/ ; }' -i "" and an additional manual change to nsINode.cpp.
