Get rid of coffeescript

[razzeee]

Roadmap or todo suggestion

Detailed Description

Migrate the project from coffeescript to javascript. Possibly to other languages after that.

Context

The coffeescript community is getting smaller and we don't seem to have devs that actually use it. While we do have some that are using js or ts.

Possible Implementation

There is https://github.com/decaffeinate/decaffeinate which seems to parse the whole project fine but one file.

But as the current master is not building on my pc, I end up with the same problem here. Due to the grunt eco step.

Note: Team Kodi will consider this item however we will not make any promises if it will be included.
