Allow searching by name #2
Description
The search bar currently searches by block height, block hash, txid, and address. We should add the ability to search by name identifier. Initially, the search can simply direct users to the latest confirmed txid for that name, per the name_history RPC method. The name_history code may be portable from https://github.com/xaya/btc-rpc-explorer/tree/xaya-develop .
