Convert editing/deleting/delete-block-content-00[123].html to use w3c test harness
This patch converts "editing/deleting/delete-block-content-00[123].html" to use
w3c test harness to simplify test files by consolidating them into
"delete-block-content.html".
Note: "delete-block-content-003.html" is identical to
"delete-block-content-002.html" expect for 003.html has two DIV[id=root].
This patch is a preparation of getting rid of grammar checking feature.
