When using `listsinceblock` to fetch transactions since the last record observed, there is a relevant detail missed that I would like to record in the ledger: `blockheight`.

It is unreasonable for my wallet interface to do an RPC lookup for every new blockhash just to get the height number. There could be hundreds of transactions or even thousands and they could all be processed with a simple call to `listsinceblock` if it wasn't for the lack of `blockheight`.

Currently it looks like:

> "blockhash": "0000000000000000000549800794b27ab10d5e16ac6ad16a7c4a13dae756f80d",
> "blockindex": 1120,
> "blocktime": 1572073467,

I would like it to look like:

> "blockhash": "0000000000000000000549800794b27ab10d5e16ac6ad16a7c4a13dae756f80d",
> "blockindex": 1120,
> "blocktime": 1572073467,
> "blockheight": 601091,

I have the same request regarding the output of `gettransaction` also.

Thanks in advance.
