[TYPO3-core] Only limited languages for frontend applications available

[Daniel Alder]

Dear all

Please see another important bug in the language handling (TYPO3 4.6 to 
6.1):
http://forge.typo3.org/issues/48674

Since I am not aware of the initial intentions there is no patch. From 
my point of view the only solution for now is to revert this changes.

Any idea what was this change for, maybe Xavier?

Thanks!
