FE: Print pick slips for service point on demand

User story:

So that I know which items need to be pulled from the shelves

Developer's update

In order for pick-slips to be printed correctly, the whole content of a template must be wrapped in a new multiple-items block:

This new pair of tokens is not included in the list of available tokens yet, so at this point they have to be added to templates manually.
