Restyle entire site

Restyling was accomplished by rewriting base.css

Also add a div between section#content and it's actual content. From the
template:

    <section id='content'>
        <div>
            {% block body %}<h1>REPLACE ME</h1>{% endblock %}
        </div>
    </section>
Update styles for login page

Login page now has a style that matches the rest of the site. A new stylesheet
has been created: site-wide.css. It contains... site-wide rules, such as the
font-family and background image.
Set styles for buttons and text inputs

Also adjust the color of several elements and padding on the calendar.
