Removed all outputing functionality.

All of the output-writing code was removed, because it will be
contained in our plugins.

We don't need to have it inline:

* Outputing of /index.rss + /index.html
* Outputing of the /tags/ structure.
* Outputing of the /archive/ hierarchy.
Added plugin.

This proves our global data-structure can be updated, which closes #2.
Added a plugin for /archive/ handling.

This closes #5.
Added plugin for /tags/ handling.

This closes #4.
Added /index.html plugin.
Added plugin to generate blog-posts.
Updated to use the newer encoding method.

This silences the perlcritic warning.
