[TYPO3-english] Get localization labels in FE without piBase->getLL

[Viktor Livakivskyi]

Hi, List.

Maybe, I'm too tired (or stupid...), but I can't get, how can I use the 
power of TYPO3 localization in FE, if I want to use some custom ll-file in 
custom object.

If I use t3lib_div::readLLfile() - it works fine, but it just reads the 
file, so I need to extract language array, merge it with 'default' by 
myself. Then I need to take [$lang][0]['target'] parts of array to get the 
final labels. That doesn't look nice.
My first thought was to pass object of 'tslib_pibase' to my custom class as 
$caller, then fill $caller->LOCAL_LANG with data from 
t3lib_div::readLLfile() and use $caller->pi_getLL(). That's better, but 
still not perfect, since I don't want my class to depend on tslib_pibase.
Another thought was to create object of 'language' class, use it's 
includeLLFile and getLL, which perfectly fits, but this class is for BE 
only. SO, it is not good idea to use it at FE?

Can someone point me, please? I'm stuck here...
