More useful editor layout

Having the graph on top of everything else makes it hard to use, since you always have to scroll down.

The layout should be changed to something more familiar, that also works better on a widescreen display. Having the tools as icons on the left side of the graph and the interfaces and menus on the right side.

It would also be good, to have all the tools and menus on one side.

The important idea: Having a horizontal, instead of vertical layout. (or make it adjust to the browser window size, so it switches between both layouts)
