Print Queue recipes#314

A really handy feature would be, to be able to save the print queue as a kind of recipe.

Then one could later with just one click put all the files from that recipe into a print queue with the amount needed for every file already filled out like in the recipe.

And then it would be nice to be able to put the recipe x times into the print queue and automatically update the amounts for each file:

recipe:
file_1: 3x
file_2: 2x
file_3: 4x

put recipe 3x into print queue, results in:
file_1: 9x
file_2: 6x
file_3: 12x

landing in the queue
