Given that:
* stair stepping is intended to be used to reduce the adhesion between support and the model, where the support rests on the model, and to reduce scarring, and
* PVA doesn't suffer from scarring or adhesion issues due to its water-solubility, and
* our current stair stepping algorithm has some bugs, causing support to disappear sometimes
we've decided to set stair stepping to 0 for all PVA profiles for UM3, UMS5 and UMS3.

This is necessary because our ContainerTree class can only create one tree per definition. This tree is not created separately for every added printer and as such the tree can't be different for every added printer.
However the Ultimaker 2 Olsson block upgrade allows selecting extra variants for the UM2. This changes the available variants in the container tree, so this would be impossible.
By making it a separate definition, it now gets a separate tree. However this does mean that we need to do a version upgrade for this as well.

I've been having this profile added via a symlink so that it would update itself. I didn't know that symlinks were possible in Git.

Otherwise these profiles won't get loaded.
The change necessary to perform this version upgrade is to rename support_minimal_diameter to support_tower_maximum_supported_diameter, but none of these profiles override that setting so no other changes are required.
