Cast vote on proposal creation

[NoahSaso]

Resolves #798

This allows the proposer to cast a vote when creating a proposal, which also takes care of instant-passing proposals when the member with majority voting power proposes something (#759). It will fail if the proposer is not a member (when anyone may propose is enabled).

It works by simply chaining the vote execution function after the proposal creation. This makes it future proof by respecting all other relevant features (such as min_voting_period and allow_revoting, which would have been ignored by #776).
