Update SQF/dayz_code/stringtable.xml

Updated stringtable.xml (dev branch) with translations : Spanish (from Sharkiller : https://github.com/R4Z0R49/DayZMod/issues/135); Dutch (from Markolie : https://github.com/R4Z0R49/DayZMod/issues/150) and French (from me : https://github.com/R4Z0R49/DayZMod/issues/244) 


Also,

I've found something strange in the new food types : 

Look at the STR_FOODCOOKED_EQIP_CODE_NAME_1 / STR_FOODCOOKED_EQUIP_CODE_DESC_1 (1249/1256) and STR_FOOD_EQIP_CODE_NAME_1 / STR_FOOD_EQUIP_CODE_DESC_1 (1170/1179) maybe there's an inversion between Goat and Mutton in the original lines.

And STR_FOOD_EQUIP_CODE_DESC_4 (1233) seems the same as STR_FOODCOOKED_EQUIP_CODE_DESC_4 (1305) (raw/cooked)

Cheers !
