[TYPO3-content-rendering] Divide css_styled_content in multiple templates to rid ourselves of the compat versions

[Franz Koch]

Hey Susanne,
>> the current css_styled_content version has a lot of compat version 
>> conditions in it. 
> 
>> 2.) Make a whole template for each version, so it's like:
>> - css_styled_content 4.3
>> - css_styled_content 4.2
>> - css_styled_content 4.1
>> - css_styled_content 4.0
> 
> I just finished first version of a divided css_styled_content. Attached 
> is the patch. Pls try it and tell me what you think of it.

thanks for your work. But unfortunately I'm currently out of time - so I 
can test it. But I'll do my best to give feedback soon.
