MegaPlots mostly done now

Fixed up methods throwing errors when not merged properly
Plot merge command now merges plots as far as the plugin is concerned
- Roads are not removed between the plots
- No way to unlink a merged plot

Added plot delete command (permission: plots.clear.delete)
Modified plot clear to simply clear the terrain.
