HTML 5.0 support

[azaozz]

All HTML 5.0 block tags have been added in both versions of wpautop(), even tags that aren't fully supported in any browser yet and as of [17625] TinyMCE recognizes all HTML 5.0 tags too.

This ticket is for correcting issues with the HTML 5.0 support in WordPress' general workflow (writing, editing, formatting) and writing testcases for it.

On the HTML 5 general workflow in WordPress:

List on "remove invalid parent paragraphs" might need updating.

blocklist1 and blocklist2 are HTML 5 unaware during switchEditors

Changing type to defect (bug) since that's what ticket is meant to collect.

List on "remove invalid parent paragraphs" might need updating.

I suspect this is fixed (not needed) in the current TinyMCE, needs a bit more testing before we take it out.

blocklist1 and blocklist2 are HTML 5 unaware during switchEditors

Needs more testing to confirm how to handle the new block element tags (and probably improve the current blocks that can contain another block).

@azaozz - this might be done, if you wouldn't mind taking a quick look

Yep, fixed in different commits over several releases. This ticket was far too broad.
