Provide twiddle credentials external to the command line

A feature request to update Twiddle to read options from a property file has been included in the latest release of JBoss Enterprise Application Platform. Twiddle can now read its options from a property file using the syntax below: <programlisting> twiddle -P <file_name>, --properties=<file_name> </programlisting> Command line options are: twiddle.user, twiddle.password, twiddle.server, twiddle.adapter and twiddle.command. Options manually supplied on the command line override duplicates from the file, anything else is set as a system property.
