Currently Liferay.dev requires this URL rewrite configuration for Questions: https://github.com/liferay/liferay-community-site/blob/3a64b5bc9fb2369d4a3f6013f349e1294af1781b/liferay/configs/common/tomcat/webapps/ROOT/WEB-INF/urlrewrite.xml#L26

The goal of this story is to introduce a friendly URL mapper in Questions that makes that configuration unnecessary. 

If this didn't work, as Plan B we could apply Liferay.dev's configuration to master (see https://github.com/liferay/liferay-portal/blob/master/portal-web/docroot/WEB-INF/urlrewrite.xml)

How to test it

• Change to history router in MBMessage configuration in System Settings. Add a path like '/ask'
• Add Questions Widget to a page. Rename the page friendly URL to the same as the history router: '/ask'
• Check the paths the widget generates and how the history router works without modifying the url-rewrite.xml
