Hi, There are no graphics when the generators are builded for 2.1 version

i have fixed this:

prototype/entity.lua

find

horizontal_animation = animation(tint),
vertical_animation = animation(tint),

and relpace

pictures = {
north = {
animation = animation(tint),
},
east = {
animation = animation(tint),
},
south = {
animation = animation(tint),
},
west = {
animation = animation(tint),
},
},

seems like luals used the wrong docs/jsons so this slipped through. Also the tier icons didn't work as intended. Both fixed in new version.
