Use Google webfonts and adjust font choices

Now using Lora instead of Georgia.
Add requirements.txt (possibly incomplete)
Redesign homepage
Ignore media/ directory
Update Article/Category models

Can now upload images, among others.
Show Article objects on homepage

(Instead of the fake articles I had before)

(Though these are still fake articles)
Add basic article view
Increase hyperlink area for homepage articles
Change top offset for homepage article overlays

Figured out the actual top offset instead of just blindly guessing.
Though this is only properly vertically aligned until the user zooms
in or out.
