Admin Overhaul and tagging

I have finally gotten around to overhauling the admin area and add tagging.

The admin area is completely new. It is much easier to navigate, and is a strong base to build on. I have also switched out TinyMCE for SummerNote editor; loving it so far. TinyMCE was just a pain to include and work with.

I have also added tagging with categories coming soon. It will allow me to organize content a little better.

Next up is adding a payload that I can download and sign with my gpg key and reupload. The idea being a javascript library would verify the payload on the front end. I am also looking to add page support for more evergreen content.
