* Add "heredoc" style quoting.
* Added POSIX style '=value' suffixes to --parameters. Thus '--foo=bar'
is now equivalent to '-foo bar'.
* Added AppConfig::CGI module to parse CGI script parameters.
* Added cgi() delegate method to AppConfig to instantiate and call
AppConfig::CGI.
* Provide default options for LIST and HASH data types.
* Allow '$' to be escaped (e.g. \$) to suppress variable expansion in files.
* Applied patch from John Salmon to allow comments to appear anywhere
on a line, not just at the beginning.
