Temporarily pin New Relic

Due to a bug found in New Relic 3.4.1, this change temporarily pins
New Relic to version 3.4.1.  This should be removed once 3.5 is
release.

Override Tomcat logging

Previously much of Tomcat's internal logging was output to files.
This log content was not accessible via `cf logs`.  This change causes
all of Tomcat's output to go to console which is then collected and
displayed via `cf logs`.
