Closes #96

The Origin types look great.
But I don't think we need it necessarily need it in the Committee pallet as extra config type, since we can check for inclusion in the Members directly. Because we check for inclusion anyway

[mattsse]

Since only members are allowed to vote, I believe we should only check for inclusion in Members instead adding another origin, which will probably do the same as ensure_member

[clearloop]

ur right LOL, added an origin for Vote created a lot of trouble for me QAQ

But the logic of EnsureMember contains the logic of ensure_member, so I want to remove ensure_member crazily LOL

BTW, I'm not afraid of Origin anymore now hhh

This is also a confusing thing while I working on this PR, the difference between our pallet-committee and pallet-collective of substrate is: we don't need to call propose, vote, close outside pallet-committee, so the ProposalSubmissionOrigin and ProposalExecutionOrigin might also not necessary

But for pallets like asset-index, add or remove asset, we might need the EnsureMember provided by this pallet.

How do you like removing ProposalSubmissionOrigin and ProposalExecutionOrigin @mattsse ?

[mattsse]

It's intended that anyone can submit a proposal, so this should just be the standard EnsureSigned

You're probably right, however this may change, so my feeling is we should keep the origins in

[mattsse]

This should be EnsureSigned only since, anyone is allowed to submit proposals

Suggested change

	type ProposalSubmissionOrigin = EnsureMember<Self>;
	type ProposalSubmissionOrigin = EnsureSigned;
