Multi Localization support

[LinXP]

Proposal to add support for multi-localizations for translating the plugin interface to other languages

[Predelnik]

There is technically some support -- every string used in plugin is in STRINGTABLE resource, which was used for some sort of translation to Russian by some enthusiasts I believe, but to go beyond that at least something basic from Notepad++ itself is required, currently I think there's no even a method to find out which language is used in N++ itself through API.
