Horizon libraries and tools

[mglukhovsky]

There are a number of Horizon tools that are popping up on GitHub. For example:

• lovli.js -- a boilerplate for developing react+redux applications with rethinkdb/horizo
• react-horizon -- React bindings for rethinkdb/horizon.
• react-hz -- React Horizon makes it easier to use your React application with horizon.io realtime backend.
• horizontal -- example of Vue.js and Horizon.
• elm-horizon -- WIP integration of Elm and Horizon.
• ember-cli-horizon -- An Ember service for managing a Horizon connection, and an adapter to request data from that connection.

There are probably a few more that I'm missing from this list.

We should have a list of example Horizon projects, and useful libraries and tools in the ecosystem.
