patch for org.apache.fop.apps.Options

[Richard Frazer <Ri...@haht.com>]

Here's a patch so that the Options class can take an InputStream for a user
config instead of a File object.  I found this useful when templating my
config file and replacing macros before passing it into the Options
constructor.  Please submit if you find it useful.
