* Added new rule AddHeaderDirectoryToHaikuImage that copies header

directories. Note that you need an updated "sed" (from the Haiku
  repository) if you want to use that rule.
* The "Development" optional package now installs the Haiku headers
  needed to build stuff (ie. "os", "gnu", and "posix"). It also makes
  a symlink "be" so that we can still use the BeOS compiler with its
  builtin header paths.
* Fixed AddVariableToScript for older shells that do not support '+='.
