Update tracks.rs (#119)

Changes to Treasurer, Big Spender, Medium Spender and Small Spender
Confirmation Periods as per:
polkadot-fellows/RFCs#20

I opted to not propose to remove the Big Spender track (it was part of
the discussion on RFC 20) as I am not sure how it would affect referenda
that are currently live on that Track.
