WIP: Whiten and simplify more icons in preparation of foreground only icons

• change foreground to 100% opacity for some icons
• change background color for Etar and Pocketmaps to one of the template colors
• simplify svg: convert texts to paths, strokes to paths (to get rid of matrix transforms)
• In total edited 132 icons (chromatic and monochromatic svgs and pngs …):
