Fix the main site link in the top navigation bar.

Needs to have a trailing slash for a locally served site for development.
Fixes issue #14.
Adds link to Categories in the sidebar
Fixes disqus IDs to be (more) unqiue across a site.

Fixes issue #22 by prefixing the article's slug with year and month. This is still not guaranteed to be unique, but anything other than the URL hardly is, and the point of not using the URL is to protect from future changes of the URL (such as from moving to a different URL layout for the site). The date of a post, at least up to year and month, is hopefully highly unlikely to change once comments start accumulating (if it does prior to the first comment, that doesn't matter, really).
Adds HTML5 time tag

The time tag is used to inform the article's and pages publication.
Make Disqus IDs and their prefixes configurable.
Added documentation of Disqus config variables.
Enable comment counts to be controlled by config variable.

Specifically, introduce a config variable DISQUS_DISPLAY_COUNTS. If DISQUS_SITENAME is set and DISQUS_DISPLAY_COUNTS is true, show Disqus-powered comment counts on the index page. This fixes #23.
Added documentation on enabling comment counts.
Removes the pubdate attribute
Fixed tags icon in sidebar.

Not sure how that got left out of commit 4ae6c681852cbad417c3112944f74e41bec8cb9a. I thought I had included it there?
