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
As for Arabic numeral vs roman, well, I simply took a look at the Hebrew wikipedia.

* Italian entries should be good now thanks to Ricciardino.

* Spanish fixes are only obvious typo on already grammatically correct Legolasindar's fixes.

Renamed various variables and reworked some of the branches within the code.

Hmm the words seem correct... but im not sure that is how someone would write it in portoguese..
I will ask my friend, he knows better than me.
I think something like ammo truck would be HEMTT de munição,
I dont really know the proper grammar in Portuguese though
I will get back to you about it
edit yeah it should be:
HEMMT de munições
everything is supposed to be like de (of) <whatever the type is>
(I belive, but if any brasillians that know it better than I correct me then they are right)
