Redmine

This patch improves use of html elements on project landing page.

• wrapps all kind of "labels" in <span class="label">...</span>
  • e.g. the member roles in the member box
• changes content of the member box to one paragraph per role instead of one paragraph for all roles
• wraps news comment label in a <span class="comments">...</span>

This is useful if you'd like to bolden the member roles for example.
