Get weld bootstrapped in Tomcat (save under META-INF/context.xml)

context.xml

<!--
     This context.xml causes Tomcat to insert Weld's CDI BeanManager into
     the JNDI context at java:/comp/env/BeanManager. This is required in
     Tomcat because Weld's normal boostrap doesn't work: the JNDI context
     is read-only to the webapp.

     For details, see http://docs.jboss.org/weld/reference/1.0.0/en-US/html/environments.html
