Title: Set canonical URL for details page.

Since this app includes various parameters in the URL when linking to a
location's details page, we can end up with many URLs that display the
same content. To gain more control over which URL appears in Google search
results, we can use the element with the "rel=canonical" attribute in the

section of the page.
