Something like that. It is a populist party, their main ideas are removing politicians' privileges, cutting costs and paychecks, only electing honest people and so on.
The constitution will stay the same but status quo will likely change anyway as there will be a new government for the time being and then elections soon. Also, the "No" has been mainly used to end Renzi's government by very different parties (also from the leftist area of the same Democratic Party lead by Renzi), which don't agree on many different issues and won't be able to create a government after the elections.
Not at all. Referendums on international treaties are not allowed in Italy.
The vote could indicate a rise of the populist leaders (Beppe Grillo of M5S, Matteo Salvini of North League), who usually make remarks and slogans against EU and euro.
