Allow for multiple regexes per action

[ewjmulder]

Very common scenario:

• Turn on 1 light with id: "Turn on light 1"
• Turn on all lights: "Turn on the lights"

These can easily be represented by 1 action + converter + executor in the backend, since with one you just take a list of size 1. But now we have 1 regex per action. You could try to write a regex that matches both scentences and be damned with regex issues later. Or we can introduce a new feature: multiple regexes per action.

Details:

• Allow for set of regexes per action in framework
• Also still have easy option of providing just one
• Identify the regex by some id (String)
• At conversion, you get the id so you know what to parse
• After conversion, model and executor are generic so don't need to know about the original distinction
