[TYPO3-core] RFC #15844: Use HTML5 as the default TYPO3 Backend doktype

[Steffen Gebert]

> Branch: trunk only
> BT reference: http://bugs.typo3.org/view.php?id=15844
>
> Description:
> With TYPO3 4.4, we introduced the option of allowing HTML 5 modules in
> the backend. I'd like to go one step further and switch to HTML5 as
> default. This is a prerequisite for a lot of good future developments
> like a multiple uploader in the BE with having Flash as fallback for all
> old browsers. Also, it also signals that we're not using just old
> technologies but are willing to push latest technologies as well (of
> course with fallbacks, we all know :)).

The only problem I found is with some table constructs, where table 
cells with a 1px clear.gif are larger (visible for the horizontal lines 
in CSMs and larger spaces in TCEforms).

Kind regards
Steffen
