Posteffects are multiplied by rearranging them in the editor

[klepto2]

When you add Posteffects in the worldsettings dialog and reorder them. they are added mlutiple times to the cameras.

At first when you reorder the effects it looks correct, but if you close the dialog and refresh the perspective viewport you can see artifacts and multiplied effects, eg the godrays will get brighter and brighter. When you reopen the settings you now see the effects multiple times (multiplied by the numbers of reorders you did previosly)

Before reordering:

And after reordering multiple times:

As an addtional request hidden in here: Expand the posteffect api with Remove and sorting capabilities. Currently you can only add the posteffects and clear all, but not remove single items.

This will be fixed in a build later today.
