Convert editing/pasteboard/pasteboard/paste-4038267-fix.html.html to use w3c test harness
This patch converts "editing/pasteboard/merge-end-blockquote.html" to use w3c
test harness and rename "insert_interchange_newline_crash.html" to to simplify
test files, since this test verifies "insertHTML" command instead of "paste".
This patch is a preparation of getting rid of grammar checking feature.
