Commands relate, unrelate, duplicate, and supersede now properly
use RPC Update when daemonClient is available, instead of always
calling store.UpdateIssue() directly and bypassing the daemon.
Added RelatesTo, DuplicateOf, and SupersededBy fields to UpdateArgs
in the RPC protocol, and updated server_issues_epics.go to handle them.
