feat: implicit convert BooleanT to NumberT

Also adds implicit conversion configuration option to Type constructor,
  and institutes a numbers-only bundle, and supports argument matching
  with implicit conversions.

  Still need to test that a behavior that invokes implicit conversion ends up
  with the conversion operation as a dependency (and so regenerates itself if
  the conversion changes).
