Paus button and menus

[Lubricus]

The paus function in Factorio is mostly confusing and not especially useful. You don't see how to unpause the game when you accidentally have pressed space+shift.
I propose to remove the pause function and that we instead use "escape" key to get to the game menu as in most fps/rts games. Alternative we could at least have the resume button also unpause the game.
An alternative route is to make the pause function more useful like allow move around and look in map view when the game is paused.
