Use beempy to post to steem and hive respectively

It passed the test yesterday that we can post to steem and hive with `beempy`.

You need to specify a API node. If you specify a steem node, it will be sent to the steem blockchain; if you specify a hive node, it will be sent to the hive blockchain
