Subject: MembershipType -> Membership, also used for JoinState

Instead of being defined independently, JoinState now uses values from
the Membership enumeration (former MemberEventContent::MembershipType)
that was moved to quotient_common.h for that purpose. Both enumerations
gained a Q_FLAG_NS decoration and operator<< overrides that strip
"Quotient::" prefix when dumping member/join state values to the log -
obviating toCString(JoinState) along the way. Quotient::MembershipType
alias is deprecated from now.
