An update to use Blossom 3.1.1, should:

• Update to Magnolia 5.4.2
• Update to Spring 4.2.1
• Add dependency on the site module and its app
• Change configuration to use SiteAwareFreemarkerRenderer and keep previous configuration with instructions on how to switch
• Preconfigure the usual templating functions classes for all renderers
• Switch from JSP to Freemarker for the page template

To work around MAGNOLIA-6393 a dependency on magnolia-ui-dialog 5.4.2 had to be added.

To work around MGNLSITE-40 a bootstrap file for config:/modules/site/config/site had to be added.
