Freemarker templates in web files should support auto-completion of tags

Freemarker templates in web files should get auto-completion of tags in IDEs. This can be achieved by adding the following dependency by default to the bootstrap/webfiles/pom.xml file in the archetype:

<dependency>
<groupId>org.onehippo.cms7.hst.dependencies</groupId>
<artifactId>hst-client-dependencies</artifactId>
<type>pom</type>
<scope>provided</scope>
</dependency>
