make settings daisy-themes ordered by name

[andelo]

daisy theme names are in random order(?), would be better to have them listed alphabetically.

also you can add horizontal rule by including and empty list entry like this.

{
  "caption": "Light",
  "value": "light"
},
{
  "caption": "Dark",
  "value": "dark"
},
{}, <---  inserts a <hr>-tag
{
  "caption": "Cupcake",
  "value": "cupcake"
},
