Shelf Control Modular System

This mod creates a better overview in the pie menu structure for some objects in the game, e.g. sim, computer, TV, stereo, fridge, stove, mirror etc... The main goal is to make the search faster with suitable icons. In addition, the priority of unimportant folders has been decreased and the priority of the important folder has been increased instead. A few new overcategories were also created on the computer and the sub-folders reorganized.
