ANT_HOME is used for ant

ANT_HOME environment variable appears to take precedence over which version of Ant is configured as the builder.

ANT_HOME pointed to a 1.6.2 version. I was getting a Class org.apache.tools.ant.taskdefs.ConditionTask doesn't support the "else" attribute error, even though the builder was version 1.6.5. Once I reset the variable and restarted tomcat, everything worked properly.
