new command line option for specifying  Localizable.strings path

Hi,
Some iOS apps do not use single Localizable.strings,but the strings are distributed in many files. 
In this case, one can collate all *.strings files into a single Localizable.strings file, which can be stored somewhere. 

This new command line option helps to specify the outside (full) path for such consolidated Localizable.strings.

Cheers,
Muthu
