implement a `shouldExecute` function in genesisProtocol

[tsuberim]

Implement a function that checks if a proposal is after it's defined time period and needs to be executed (as per the discussion at: https://github.com/daostack/arc.js/issues/169). Use genesisProtocol.execute.call(..).

@dev-matan-tsuberi Just checking: Are there any outstanding questions that need to be resolved about this? And do we still want this in Arc.js? Thanks.

[tsuberim]

No. Yes. I think we settled on having a function like that in Arc.js and an "Execute" button in alchemy.

I actually think we settled on not showing these proposals at all in Alchemy :) so we may not need this.

[tsuberim]

When have we decided that?

@dev-matan-tsuberi it was adam's suggestion, and it makes sense to me. I do want to talk more about it with Aaron though a bit more

[dkent600]

OK, I'm moving this down on the priority list.
