[TYPO3-4-3] Get rid of dependency of static_info_tables

[Steffen Kamper]

Hi,

there is a hardcoded dependency to static_info_tables in core. As soon 
flexforms are used, they use the ISO_3166-1 alpha2 code as language-key

sDEF - default
s[ISO-code] - translation

Now, as this is the only information core needs from static_info_tables, 
we can integrate a flat list with these codes, this would make things 
much easier.

I prepared a first patch doing this:
http://bugs.typo3.org/view.php?id=13539

Note: the filed is changed to varchar, as now the ISO code is saved in 
the field (not the uid of the static_language record)
This is different to usage with static_info_tables.

As static_info_tables overwrites the TCA of the field, both are not 
compatible. So i left the check for isloaded in core, but fill ISO also 
without loaded extension.
Problems will be for now the switch having existing language records. 
This has to be solved, but first i want to hear your opinion.
