Add:
        templates/index.html, static/sass/index.sass,
        static/img/index/search_bar_magnifying_glass.png
                -Replace the magnifying-glass advanced-search icon with a simple
                textual button.

        static/(js/index.js, sass/index.sass)
                -Slightly modify the appearance of error messages; add message
                for no results.

Add:
        bitshift/assets.py, static/sass/404.sass
                -Add `syntax_highlight()` and style rules to perform syntax
                highlighting on 404 error messages; used in
                `templates/error404.html`.

        templates
                -Add a `Jinja` expression to select a random "404" message from
                a sequence.

Add:
        static/img/about/bio*.jpg
                -Scale bio images to a smaller size, from 500x500px to
                200x200px, as they were far larger than necessary for their
                dimensions on the about page.

Add:
        templates/about.html
                -Replace filler text with real biographies.
                -Make all images hyperlinks to our `GitHub`s.

        static/img/about/bio(1, 2, 3).jpg
                -Update biography images with our headshots.

Add:
        static/js/index.js
                -7f4cd92 didn't fully fix the incorrect `codelet` attribute
                names in `createResult()`; second attempt.

Add:
        static/js/index.js
                -Modify functions to add actual result codelets to the `results`
                column: redefine `populateResults()` as a wrapper for
                `loadMoreResults()`, introduce a `Deferred` return-type to
                `queryServer()`, and change some incorrect object field names
                (eg, "html_code", which should've been "code") in
                `createResult()`.

Fix:
        static/sass/index.sass
                -Allow codelet-scrolling, and modify result component widths.

Add:
        templates/about.html, static/sass/about.sass
                -Change parallax image offsets and scroll speeds; current
                implementation still isn't scalable to different resolutions
                (it'll work for most, but not all).

Add:
        templates/about.html, static/sass/about.sass
                -Add biography-section HTML structure and styling, containing
                filler images and lorem ipsum; now, it's just a matter of
                substituting in the appropriate content.

        static/img/about.bio(1, 2, 3).jpg
                -Add placeholder bio images.

Add:
        templates/index.html, static/sass/index.sass
                -Move the "add group" and "remove group" buttons inside the
                advanced-search form to a different location.

        static/img/index/
                -Following convention established by the "about" page, all
                page-specific images should be located in a subdirectory of
                `static/img/` named after the page. Add `index` dir.

Add search-engine files, a favicon, and 404 page. Close #70, #71.

Add:
        app.py, templates/error404.html, static/sass/error404.sass
                -Add Flask 404 handler and styled 404 page.

Add:
        app.py
                -Remove hard-coded routes for files in the application's "root"
                (`static/`) directory; redefined Flask's `static_url_path`
                accordingly. Files can now be directly accessed by URL.

        bitshift/assets.py
                -Remove the `static/` prepended to all resource paths.

Add:
        static/js/main.js
                -Add a global javascript file, with bitshift's Google Analytics
                snippet.

        static/google10335120a3066831.html
                -Add our Google "Administrator Console" authentication.

Add:
        static/img/favicon.ico
                -Add a favicon.

        static/(robots.txt, sitemap.xml)
                -Add search-engine files. `bitshift` is not yet registered with
                Google.

Add a styled and mostly content-complete about page.

Add:
        static/js/about.js, static/sass/(index, about).sass
                -Minor cleanup before merge into `develop`: remove a superfluous
                style rule, update header comments.

Add:
        templates/about.html, static/sass/about.sass
                -Add text to the about page, and the necessary styling for it.

        app.py, templates/layout.html
                -Add an automated copyright year loader.

Add:
        templates/about.html, static/js/about.js
                -Add a `speed` attribute to all image divs, which is used to
                determine the rate at which an image moves upward.

        static/img/about/bg2.png
                -Change image to another source-code screenshot.
