SIP 00049: Clarify Quorum Definitions

For 'Basic' Strategy (ie For/Against/Abstain) SharkDAO & "Propose to NounsDAO" proposals let Quorum be defined by "Total # of 'For' votes cast."

For "NounsDAO Vote" proposals let Quorum be defined by "Total # of either 'For', 'Against' or 'Abstain' votes cast, whichever is greatest." If Quorum is not met in a NounsDAO Vote proposal, SharkDAO will vote 'Abstain.'

'Approval,' 'Ranked Choice,' 'Weighted Vote,' and 'Quad' Voting Strategies may be used as sentiment signaling tools and will not be construed as binding until DAO can establish well-formed programmatic guidelines for determining Quorum & proposal validity.
