Undo misses the block-level changes.

[shrikant-joshi]

Reproduction steps:

1. Make a block-level change, e.g blockquote the first para.
2. Make a word-level change, e.g. bold a letter or two, underline something.
3. Make another block-level change, e.g. change the second para to h1.
4. Hit Ctrl-Z (Winows/Linux) to undo.

Only the change that occurs in step 2 is undone.

PS: Great work, nonetheless! I was looking for something like this for the landing page on my site. :)

The problem is undo only works with execCommand. So we need to change the way we create h1/q, using formatBlock, or implement the undo behavior manually.

Should be fixed now
