Adding more tags to aid navigation.
site.hs now supports multiple "blogs".

Each blog can co-exist on the same site, using the same Hakyll templates
so there's less Repeating Yourself.

The only issue at the moment is that posts, tags which appear in more
than one blog aren't duplicated to both blogs.
There may be other such quirks where blogs aren't mutually exclusive
with content.
Updated default template to link to both blogs.
Token blogpost for other blog.
