Subject: [PATCH] failOnError and showOutput attributes for <rpm>

Submitted by:	Zach Garner <zach at awarix dot com>

In Ant 1.6.2 <rpm> wouldn't fail even if the command failed, CVS HEAD
would fail unconditionally if the command failed.  If chose 1.6.2's
behavior as default for failOnError (i.e. it is false by default).
