This also updates all other plugins that rely on process listing and theoretically allows them to choose their preferred method of process listing. At the moment, the default (first in the method list) is chosen. An optional pslist_method StringRequirement can be added to each plugin, but using the list in the requirements could break if the pslist plugin is too old (ie, using the list would happen before the PluginRequirement gets checked). If this is a feature we want, it should be easy to add to all but netstat, which does not parameterize the list of processes.
