PCA Plots 0.1.2 (permissions)

New

• Being a teacher in the plot world (building anywhere, /plot admin) is now the Forge permission pcaplots.teacher, so a permissions mod can give it without making someone an op. By default it's still ops plus PCA Classroom's teachers, so nothing changes without a permissions mod.
• Works with PCA Perms: its teacher group has pcaplots.teacher from the start.
