Templating in custom labels

[cgiesche]

I love your idea. Currently, i use handlebars as templating engine, which is very basic and clean but lacks some features that would be very useful in context of this project.

I will take a look at https://github.com/sstur/jinja-js, which is a javascript implementation of the templating engine that home-assistant uses.

An architectural challenge is, that (currently) in context of a button, i only have access to the state of a single entity. I think combining the states of different entities would be great, too, but would require a rework of big portions of the code.

I will create two issues:

1. Replace handlebars by jinja-js to be able to do calculations etc. in templates (may happen soon)
2. Redesign internal state architecture to be able to access cross-entity-states inside templates (may take some time ;) )

(Spoiler) Replacing handlebars by jinja looks promising:
