AWB custom module to allow external script filters with the following features:

• summary files
• command line template, to allow sending extra arguments to external script. Most useful are: article title (URL escaped, to allow safe transfer of UTF strings) and article namespace
• custom control of child process creation details (e.g. minimized or no window at all)
