Update icons

[MX_wb]

A lot of icons are outdated, and i think it would be great if they were updated.
Fusion reactor (doesnt look like the research)
Turrets
Robots and robot frames
Modules (doesnt look like the research)
Small pump
Trains, train wagons and train stops
Rail signals
Personal roboport (doesnt look like the research)
Capsules and combat robots
Landmines (kind of)
Batteries (in power armour)
Personal laser defense
Personal solar panel

There are maybe more.

Also, some textures and icons should be changed.
Lab packs dont look like their ingredients, (copper plate + iron gear = red liquid in glass flask)
Grenades and cluster grenades look kind of bad.
Maybe concrete, you could make it look like the research instead of a tile, same with landfill, the icon could be a pile of stone
Batteries, the icons should look more 'industrial' instead of something you might get from a shop.
The electric engine looks like a combustion engine, i think it should look like the research icon.

The stone furnace looks a bit bad, and maybe the electric furnace could be improved.

I think this would improve the game a bit more, fitting with a factory, industrial theme

I know a lot of textures are changing from old ones like the turrets and stuff, but still consider the batteries and stuff

Till now every version some icons and graphics change. This is never complete.
