I'm sort of an orphan.

Tohil 4.2 fulfills on Tohil's #1 new feature request: Python code passed to tohil::exec is now unindented before being passed to Python.

• Fixed crash when register_callback-registered functions raised a Python exception.
• Added the required directory tree to build tohil as a Debian package.
• Cleaned up tohil namespace so dir(tohil) doesn't show modules tohil imported as if it had created them.
• Make 'package forget tohil' work. (hat tip to @pooryorick)
• Support tcl 'unload' command for tohil shared library. (ditto)
• Add -nonevalue option to tohil::call to allow the "none" sentinel to be arbitrarily specified. (Retains the default of tohil::NONE.)
• Homebrew formula for building with homebrew (hat tip to @midsandhighs)
• Updates to documentation and tests.
