Cell editor improvements

I dont get why all you are shown in the cell editor is a rough sillouete of your cell, why not make grid icons for each organelle? i also think it would be nice to have a kinda eraser tool.

You can remove organelles by right clicking them. As to showing the organelle models in the editor, that was in the game, but broken when we changed engines. It’s still an issue on Github, but no one has wanted to tackle it:

ahhh ok, sorry about that
