Remove duplicate recipients from Cc

When a user files a request for a package maintained by himself, he is
currently included in the Cc list twice. Use array_unique() to omit
repeated entries.

Close requests before accepting

When auto-accepting a request, we need to close the package request
before performing the actual action (disown/deletion/merge). Otherwise,
the former maintainer is not included in the Cc list of the
acceptance/rejection notification email.

Lock fresh orphan requests

Trusted Users should almost always wait for two weeks before accepting
an orphan request. Lock orphan requests during the first two weeks.
Package bases can still be orphaned and package requests can still be
closed manually during that period of time.
