Permissions reworked!
- Made most permissions default true so you don't have to be OP
- particleguides.guide.* is now particleguides.guide.limit.* and is no longer a prerequisite for using /guide. If no limit is specified, defaults to an unlimited number of guides.
- particleguides.breadcrumbs.* is now particleguides.breadcrumbs.limit.* and is no longer a prerequisite for using /breadcrumbs. If no limit is specified, defaults to unlimited length trails.
- Added particleguides.breadcrumbs (default true) to control access to breadcrumbs
- /particleguides config is now just /particleguides, requires permission particleguides.admin to use (default OP)
