Add resource links to orgDetail

When viewing an organization using orgDetail.php, it is nice to
see which resources are associated with it.  This adds that
feature.  It includes:

 - a new function in the Organization class, getResources()
 - a new utility function, getResourceRecordURL()
 - a new configuration option, resourcesDatabaseName

Adjust resource links sidebar to show all roles

The sidebar was only showing resources that used this organization as a
role that this organization had assigned to it. This allowed for
inconsistent data. For example, a resource could list EBSCO as its
publisher even if EBSCO only had the roles of vendor and provider. This
commit simplifies the user experience by showing resources with any
relationship to this organization, regardless of which roles are turned
on for the organization.

Mark archived resources in Org sidebar

The sidebar list of resource links does not indicate the status of a
resource. Katherine requested that we do something to make clear which
ones were archived, so this commit does that.
