Enginified game components

In an attempt to bring order to chaos, I started to sort our creations
into game specific(both hymn and minionmaster) and reusable.

So I created a new folder called "spiceminion_engine" including all the
"engine" files. Then I tried out to let both games run on that -> works.

Hope you like it. If you're ok with it just delete the stuff from
"shared"
