Create .Shortcuts directory if it is missing
FLOW3 currently creates or updates the Packages/.Shortcuts/ directory only if the package states have changed. That is correct in theory, but if one messes with the package directories by manually moving around packages, you might get lost.
Therefore it would be nice if the .Shortcuts directory would be created if it does not exist. This would add stability but also allow a developer to just remove a broken .Shortcuts directory and it would be regenerated on the next hit.
[FEATURE] Create .Shortcuts directory if it is missing
The .Shortcuts directory will now be built if it is missing. That allows
developers to just trash a broken .Shortcuts directory if they messed
with package directories manually.
