After over 17 years of honorable service to the Ardour Codebase.
ClickBox and AutoSpin are retiring into the git nirvana.
We're glad for the duty, decency, reliability, dignity, respect which
these classes brought to Arodur and look back in gratitude on their years
of service.
PS. First one to say "cruft" will be fired.
