m_rsc_gone
This model tracks deleted resources (see m_rsc). Its primary goal is to be able to determine if a resource never existed, has been deleted or has been replaced by another resource.
Information kept
Only very basic information of the deleted resource is kept in the rsc_gone
table. It is enough for referring to a new location, giving correct errors or
to determine who deleted a resource.
It is not enough to undelete a resource. The module mod_backup retains enough information about past versions to be able to undelete a resource. Currently there is no support for an undelete.

Whenever a m_rsc record is deleted some information from
that resource is copied to the rsc_gone table.
