align components new when position other components between them

[JaquelineP]

If you position a component over another one, align the new component below the other component. Then you have to align the other compontents (below new component), too.

I've just finished implementing this, components can now be inserted in the middle of the "data flow" and all following components will be repositioned. Additionally, once a component is dragged out of the "data flow" the gap will be closed and all components below will be moved up.
All this happens without the DataFlowAlignment components from Jens. Once I finished cleaning this up and the remaining leftovers used to work with these DataFlowAlignment components are removed, this issue can be closed.

Nice one! I feel like it would be awesome, if you re-align the components at the moment, where the preview morph snaps below a component or leaves this position. Then you have a better preview what will happen when you drop the morph. The preview morph will always create enough space for the component to fit in there, since it uses the same algorithm, so you don't have to re-align when you actually drop the morph.

Yes this sounds nice, I'll change that in a minute.

Nice!
I would be awesome, too, if you re-align components also if they resize. At the moment nothing happens if you minimize a compoment (by changing their size), the other components don't align.

Both suggestions are now implemented as well, feels very good.

Wow this developed into serious coding nightmare. I've nearly worked all day on this, several rewrites from scratch later (because it got too complicated) there now is a nicely working version :)

• components can be moved between other components
• components can be taken out of the dataflow => the produced gap will be closed
• components can be freely moved around in the dataflow (there is some flickering if you hit the top most component, we'll have to live with that for the moment)
• fans will also be moved and move all "dependent" components, so the dataflow won't be destroyed or changed

Only thing left is to be able to move fan-components, I'll implement that later as there are some additional missing parts for that, that weren't implemented when we rewrote the fan components.
