Himling event

[Athoen974]

• Decision icon has no desc localisation (it has title loc)
• Event fires no-stop as soon as I conquer the island, I do not have to click on the decision icon
• with decision icon, there is no cost, no duration, so this is just clicking untill having the reward. There is no reason why a character could not search as many times as he wants, but there should be a cost (gold for trying, and prestige loss for finding nothing) The whole event should take a few weeks with a timer preventing to go back immediatly (once a year ?)
• By the way I only got the sword, but never the armor.
• Himling sword does not appear in the list of the artifacts

• Choose to push the decision will now cost 75 cash, 100 prestige and 50 piety.
• If you've got one of the items, you can't search anymore in the ruins, so you won't be able to find/search for the other one.
• The event chain will now take two months.
• Fixed the bug with the non-stop events

All works fine now! :)
