Deprecate base tag
Currently the UriBuilder creates relative URLs in the form landing-page/sub-page.html by default.
This requires the presence of a <base /> tag in the HTML head in order to be resolved correctly when the browser is currently on a page other than the homepage.
By prefixing relative URLs with the script request path the base tag would no longer be required.
In general we should think about creating absolute URLs by default (see http://yoast.com/relative-urls-issues/)
