Peru Update, Speed Submod, Terrain Pics, Sicily, Samoa and Guyana Event Chains file

I kind of forgot to update mod DB for a while so this is a pretty big update. Major features include about 150 new province terrain pictures, 7 Peruvian Civil Wars, 4 Peruvian Constitutions, a rework of the Chincha Islands War and event chains for the Samoa Crisis, the Sulfur War and the Venezuela Crisis of 1895. In addition, a submod was added that increases performance but makes the terrain textures worse for people who prefer performance to appearance.
