Migrating tagbot to HIVE

Tagbot is an upvote bot, upvotes posts with a specific tag (or a list of tags) based on pre-defined parameters. It supports auto-replies and the global blacklist API.

Install it with PIP: pip install hive_tagbot and see the README for configuration options.

Huge thanks to @pharesim for porting steem-python to hivepy, otherwise it would be more work to migrate tagbot.

^{/cc @chitty, I know you use this one.}
