v4.1.0 Alternate Nodes
Allows user to specify more nodes, and if theres a problem with the one that they provided, it will switch to one of the alternate provided nodes.
Nodes are specified in config under alternate_nodes,
with usage being as follows:
"alternate_nodes" : ["https://api.deathwing.me", "https://api.hive.blog"],
The default provided alternate nodes are deathwing's(https://api.deathwing.me) and hive.blog's(https://api.hive.blog). If user doesn't specify the alternate_nodes, it will use those as alternate. Node will switch on error with get_account or error on posting.
