Variables like %{BuildDir} not available anymore

Eg when creating a deploy step/custom process variable %{BuildDir} doesn't work anymore. Had to change to %{ActiveProject:BuildConfig:Path}; also %{CurrentProject:...} is missing.

But in this particular case that has a disadvantage: it that takes the active project: so now when I just select a (not active) project; right click; build; it builds that project (which is ok) but right click; deploy it deploys the active project instead (so have to make it active before deploying). Cannot solve this without %{BuildDir}

This is just one symptom: not having %{BuildDir}/ %{CurrentProject:...} also effects setting up external tools for example.

This changed in recent QT creator versions, I am now at 15.0.0. So this is a regression.
