Support templating the sak tools within a toolset

The Problem To Be Solved

Describing all the elements of a SAK card, ie all the toolsets and tools can be a lot of yaml. To minimize this makes maintenance and creating a complex card with repeated tools a lot easier.

So the problem to be solved is not on a card level, but on a deeper level. The decluttering template card can't be used for templating assemblies and tools.

(Optional): Suggested Solution

The decluttering card shows how templates can be implemented. The idea is to use that format to be able to template sak-tools as part of sak-toolsets.

A simple test (2020.09.30) shows that this is possible:

if (this.config.templates) {
	if (this.config.toolsets) {
		let tools= Templates.replaceVariables(this.config.toolsets[1].variables,
                                       this.config.templates[0]);
		console.log('template, tools are: ', tools);
	}
}

with the following yaml to define the card templates:

templates:
  # Define template for an assembly with 3 tools
  - template: template1
    defaults: 
      - entity0: 0
      - entity1: 1
      - entity2: 2
    tools:
      - tool: state
         id: 4
         entity_index: '[[entity0]]'
      - tool: state
         id: 5
         entity_index: '[[entity1]]'
      - tool: state
         id: 6
         entity_index: '[[entity2]]'

toolsets:
  # Both toolsets use the first template
  - toolset: toolset1
     template: template1
      position:
        xpos: 25
        ypos: 60

  - toolset: toolset2
    template: template1
    position:
       xpos: 12.5
       ypos: 60
       variables:
         - entity0: 3
         - entity1: 4
         - entity2: 5
