Qick armour selection

this code allows a quick armour selection via right click
if one selects a armour in the soldier-armour-window its name is saved (SaveGame)
after that a rightclick in the craft armour window replaces the armour of the soldier
default armour (after game start/load) is STR_NONE_UC
if there are no further armor items available the quickselection does nothing
i would have made a replaceArmour method but was not sure where best to put it 
so we have now a bit of code duplication (SoldierArmorState does the same as CraftArmorState)
