Create a touch screen UI for product details

_Originally: https://github.com/virge-io/pricelist-frontend/issues/333_

Make a new pricelist for the Border

Duplicate a current one -> then ->
Adapt this pricelist so you can touch a price and see a touch friendly product detail page.

Tips:
- you probably use the product detail page of the KindEditor as long as you stay in EUI country.
- bonus: cool screensaver when in-active: they now use the OS screensaver; so peopel have to touch it first (which seems needed in A'dam)

No files, tests, or entry points are named. Start by locating a current pricelist to duplicate and the KindEditor product detail page referenced in the issue, then determine how the Border pricelist should open a touch-friendly detail view after a price is touched. Done means the adapted pricelist works for touch interaction; the screensaver is listed as a bonus.
