Cancel Proxy Type

[shawntabrizi]

This is a PR to introduce a new proxy type which has the power to specifically reject and remove announced proxy calls.

FYI to add this type while testing:

{
        "ProxyType": {
                "_enum": [
                        "Any",
                        "NonTransfer",
                        "Governance",
                        "Staking",
                        "IdentityJudgement",
                        "CancelProxy"
                ]
        }
}

Thanks to @jacogr for this info.

@ddorgan If you test against Polkadot (which is --dev here), you need to leave a gap after IdentityJudgement, so something like ... "Staking", "Unused", "IdentityJudgement", "CancelProxy"

@shawntabrizi No Westend?

[wpank]

Also add this to Westend and this should be good to merge I think.
