Also, remove executables (in full setup or "tidy" mode) when the
corresponding collections are removed.
As a result of these changes, `raco pkg' puts launchers from user-scoped
packages in user space and cleans up launchers from removed packages.
There's no attempt to include "launchers.rktd" in a distribution.
That should be ok: having an entry in "launchers.rktd" just
makes a launcher a candidate for removal. Including "launchers.rktd"
would be a hassle for many reasons, including that the initial set
of launchers is platform-specific.
