Title: site_title proc should be rendered in HTML title tag

If `ActiveAdmin.site_title` is a proc, it will not render properly in the HTML title tag (it will instead be the result of calling `to_s` on a `Proc` which is garbage).

This patch calls `render_or_call_method_or_proc_on` on the `site_title` before outputting it in the HTML title tag.
