[Feature] See mempool bids

[Falci]

In the bids page, I'd like to see the list of unconfirmed bids, from mempool.

This is somehow related to #179

This data may be very flimsy, remember there is no "the mempool" -- when you start up your node your mempool is empty, so you could be missing bids that were already transmitted. Bitcoin/bcoin/hsd have a p2p message mempool which is used for SPV nodes to request mempool contents from a peer when they come online, but the peer must support BIP37 (have SPV service active, which is not default).

Even if your node is on all the time you could be missing relayed TXs for networking topology reasons. This is why the blockchain is the only source of truth in the system.

Got your point. Maybe this feature could be activated under a check, where the user says that understand what it means. My point is: some information is better than no information (about the mempool)
