Updated review-bot to 2.3.1 (#132)

Updated review bot to version 2.3.1 which contains the fix for
paritytech/review-bot#107.

When a fellow's identity is empty, it will search for a sub identity and
try to extract the handle from such subidentity.

I have also added @ggwpez's brilliant site to the readme so the fellow's
can see their list of identities (as I don't have any up-to-date listing
myself).

 The review-bot uses the on-chain identity to map from a GitHub account to a Fellowship member. This requires that each Fellowship member add their GitHub handle to their on-chain identity. Check [here](docs/on-chain-identity.md) for instructions.
