Changed license to AGPL v3 or later.

This is a maintenance release updating to Go 1.22 and various package dependencies. Adds ToYAML suppport in cli.

This release contains bug fixes for the fountain sub package as well as code cleanup generally.

This release is mostly a code re-organization due to changes in how Go 1.18 supports modules. The packages osf, fountain, and fdx are now part of the scripttool. The modules are largely stable. It's been years since I've changed them. The scripttool itself has bee restructure. A major change is the command line syntax. I am now using a scripttool [-help|-version|-license] VERB [OPTIONS] [ADDITIONAL_PARAMETERS]. Each "verb" can have its own set of options and they come after the "verb" before it expected additional parameters.

The build process for source code and website have been significantly updated. I'm using Pandoc and pdtk to build the website. The old Makefile and Python scripts have been replace by a two new Makefile (i.e. Makefile, website.mak).

In the scripttool command the "characters" verb will list the characters found in a fountain formatted screenplay. By default it is order of appearance but there is now an option -alpha for alphabetical sorts.

Updates to support go1.16 modules, updated copyright year, switched to Pandoc templates for documentation and experimental M1 compiled binaries.

The fdx, osf and fountain packages are pretty stable now. Scriptool wraps them and they have been released individually. This release of scripttool is compiled against v0.0.1 of each of those packages with Go 1.12.4.

This is just a prototype of a command line tool for converting various screenplay formats.
