Painted Biomes

• Added template repeating, works only in the Single Template mode.
• You can repeat the entire template, or just the biome from the edge-most pixel of the template image.
• The repeating can be set individually in all four directions (+x, -x, +z, -z)
• The "corner areas" of the world only use repeating, if both of the sides adjacent to that area use the same repeating mode.
