add some new tutorial step more addressed to middle game accounts :
For each category, it can be done in 3 levels of development
- when you get level xx on all mines you get a set of free bronze/silver/gold boosters
- when you get xxx points in military score , you get a free bronze/silver/gold kraken
- when you get xxx points in economy , you get a bronze/silver/gold detroid
- when you get xxx points in research you get a free newtron

is not a proper tutorial, is more of an achievement recognition as it is intended for players reaching a given ( more developed) level of mines / fleet/research .
My idea is to extend what we have instead of making new additions. For this purpose the tutorial looks the most appropriate
