Peers page revamp

[olizilla]

Initial design is here: https://projects.invisionapp.com/d/main#/console/13924274/302167366/preview

The design is based on the redux'n'sagas branch over here: #229 (comment)

As a first pass please review the UI work from the redux branch and where it makes sense, port it to a branch off of revamp. The revamp branch has data in the store for peers already. It needs to be extended with logic for geoip look ups. That involves https://github.com/ipfs/ipfs-geoip and their is prior art for using it in both the master and redux branches.

In the revamp branch we're using redux-bundler to simplify our redux logic, see https://reduxbundler.com/

Of note @alanshaw is working on the peers bandwidth graph for the stats page and there is significant overlap here with that work (flags and geoip plumbing). Please co-ordinate your efforts here.

• emoji country - flags https://github.com/danalloway/react-country-flag
• ipfs-geoip - https://github.com/ipfs/ipfs-geoip - would be great to re-import the data with the latest geoip mappings.
