chat GUI for /aa_listcommands showed "PermDesc" as clickable filter option when not in multiline mode
it was not possible to disable any commands that start with // (usually WorldEdit commands) with /aa_disablecommand
the aa.bypassdeletecommand.all permission for disabling commands was actually being checked as aa.bypassdeletecommand.any, so checking for it did not work
internally checking for multiple bypass permissions (example: aa.bypassdeletecommand, aa.bypassdeletecommand.all and aa.bypassdeletecommand.say) did not always work as intended
adding a multi-level manual permission via /aa_addperm (say.badword) resulted in that permission being impossible to remove via /aa_delperm
