templates: Use uri_for to reference static paths.

This commit is provided by (zsh syntax):

sed -i 's|/static[^"]*|[% c.uri_for("&") %]|;s/\[% size %\]/${size}/' **/*.tt

And the reason for this change is to make it easier to change the base
path with headers like X-Request-Base to be served within a URI prefix,
especially when behind a reverse proxy.
