Added support for piping: 

- input from stdin (-imagein not supported)
- output to stdout

Syntax: fop -xml # -xsl mystylesheet.xsl -pdf #
(reads the XML from stdin and sends the generated PDF to stdout)

git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk@675698 13f79535-47bb-0310-9956-ffa450edef68
