[Building Sakai] Spring MVC Maven Archetype on Sakai 2.9.2

Because of https://jira.sakaiproject.org/browse/KNL-757 spring-mvc was
removed from shared in 2.9. The best thing for compatibility is to add a
profile to your tool that has this dependency, so it will work in 2.8 or
2.9. If you just want to make a branch, you don't need this profile.

  <profiles>
    <profile>
      <id>sakai-2.9</id>

      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>

      <dependencies>
        <dependency>
          <!-- must include this in the war for sakai 2.9+ -->
          <groupId>org.springframework</groupId>
          <artifactId>spring-webmvc</artifactId>
          <scope>compile</scope>
        </dependency>
      </dependencies>
    </profile>

To be compatible with trunk, there was dependencies against general spring
and hibernate. I should add that info about spring-webmvc to this page
(maybe it's already somewhere), but I figured all tools were already
upgraded.
