* Add more log entry types to the org-level logs page
all_logentries() limits the QuerySet to LogEntrys whose content object
is an Organizer.
This change expands that to get any LogEntry linked to the current
Organization. It removes those that are linked directly to an Event,
since they are already served by the event-level logs page.
* Check active plugins with either Event or Organizer
These variables effectively hardcode the location from which the script
is run. We shouldn't need these since git should know that it is inside
a repo when run.
