title: Spring-boot banner.txt variables not processed
body: <p>I don't seem to be able to get the banner.txt <code>${application.version}</code> or <code>${application.formatted-version}</code> variable processed and shown at runtime anymore.</p>
  
  <p>Banner.txt is taken into account as it displays static text I added in.</p>
  
  <p>I start the app packaged as a WAR file and it contains the <code>META-INF/MANIFEST.MF</code> which in turn contains the expected <code>Implementation-Version</code></p>
  
  <p>I'm using Spring-boot v1.3.1.RELEASE, with Tomcat 8.0.30.</p>
  
  <p>What could go wrong?</p>
