Small pieces of Rhudaur flavor

[josejuanmartinez]

• [x] Troll Blockers
• [x] A small intro popup with no action with that information about Rhudaur. I'm pretty sure lore-lovers specially of the TA 1600-1800 would appreaciate to understand who these people are.
• [x] Troll attacks coming from The Ettenmoors. I think this could affect mainly Rhudaur but also with a small random probability Imladris.
• [x] Rhudaur hunting. Mine but read a couple of people talking about this. Chain of events for Imladris and Dunadan Rangers to chase trolls and kill them, also orcs. It gives county control and development at the end in Rhudaur, and each of the events soem XP as well.
• [x] The Ettenmoors: A new wonder, acting as a big Troll blocker in the Ettenmoors, but also allowing evil_faith orcs to hire Stone Trolls.
• [x] Stone Trolls
• [x] Subjugate the Ettenmoors: decision for human or AI+not_lore_gamerule, that allows Mt. Gram for big piety and hard decision, to conolose the Ettenmoors. The blockers are not removed.
