Strategies should also have a name, and description

[bonustrack]

Currently we show strategies in the UI using their id like "erc20-balance-of", it's not so friendly, we should have a name and a short description for these strategies like "Token balance", "Voting power is based on a token ERC20 balance."

Can we do this in schema.json's title? https://github.com/snapshot-labs/snapshot-strategies/blob/master/src/strategies/erc20-balance-of/schema.json#L6
