Group objects In the Builder#289

To group together blocks that have a common goal. This will help to find, edit and add more blocks easily. Now it looks really messy when you have a lot of modules.

They have this function in Conversiobot but once you group the messages together its hard to view the flow in its entirety as you cant reverse it. this feature should be expandable at the click of a button. E.g you can choose to drag multiple blocks into one block but also have the option to expand the individual blocks out again if you want to see the messages individually as one flow
