New interaction with Rogue Exiles

Two ideas here.

1. Some Rogue Exiles aren't that hostile but as we know they all fight to death no matter what. These "friendly" or "neutral" exiles could offer us an option to disperse peacefully at the very start. If we click on "Yes", they will stay on the place as neutral NPC with whom we can trade (and they can offer some nice rares, just as those guys in the jungle camps in Act 3). If we click "No", we fight them as usual.

2. Some Rogue Exiles are hostile. These offer nothing and start fighting. However, if we beat them to (let's say) 25% HP left, they offer "Surrender" option'. Again, if we press "No", we continue to fight as usual. If we press "Yes" they will pay (drop some currency) and disappear through portal.
