HU, IT, PT, RU entries + minor FR, SP, PL fixes.

> This is a merge of #1059, #1061 and #1023

Added Hungarian, Portuguese, Italian entries so they at least have the realistic-ish names and Russian folks have the names wrote in Cyrillic, as far as I have been able to find them on Wiki.

Please note that I'm not fluent in these language, I just assume that's at least more enjoyable than plain English.

* M2A1 Slammer looks to be a Merkava Mk 4m Windbreakern which is "a Merkava Mk IV equipped with the Trophy active protection system (APS)". http://en.wikipedia.org/wiki/Merkava#Mk_IVm_Windbreaker

* Italian entries should be good now thanks to Ricciardino.

* Spanish fixes are only obvious typo on already grammatically correct Legolasindar's fixes.
Ok, it depends ... Imho, I'd say use english for all NATO members as english or french are the offical NATO languages. Or if everything should be translated to the native languages then you're right and it should be "Jak" :|

Opinions?
