I havent heard anything yet from the omertu, so i'm continuing my changes in my fork: https://github.com/p0psicles/GoogleHomeK...ee/develop

For now i've made the following changes:
- [x] Cleaned up js code, added .eslintrc
- [x] Separated server.js (routes) and kodi helper methods (into helpers.js). Moved config related code into config.js.
- [x] Used ES6 with promises, instead of passing callback functions. Makes the code cleaner, and some of the helper functions are reusable now.
- [x] Added kodi open "show". This will open the show in the GUI, allowing you to navigate into the seasons from there.
- [x] Added kodi-hosts.config.js.dist (rename to kodi-hosts.config.js) to run the node server locally instead of in Glitch.com. If the file is not renamed, it will look after the Glitch env variables.
- [x] Fix searching PVR (at least tvheadend) by channel number. Removed searching channels per channelgroup, as we can also use the "alltv" group.
- [x] Added shuffling (playing a random episode) for a specified show.
- [ ] Control multiple kodi instalations.
- [x] Search and play youtube video's.
- [x] Update the docs.
