Small fix related to missing locale lines for command list
Added support for PlotSquared, after all, we do have simple API now, so why not, its literally 40 lines of code with most of them copy/pasted from WorldEdit Polygon effect to have this support. So now you have a command like /svis plot which will show bounds of current plot you are in. Different colors will be used for plots you are not a owner. Additional, added option (enabled by default) to show plots bounds when entering player-owned plot (any player) this will display particles for a short time period, default is 2 seconds, can be set to any other length.
