Don't use "/e" in PHPMailer Lite

Summary: PHP 5.4 raises an E_STRICT warning about "/e", and it's a generally awful idea, even though this case doesn't look exploitable. Silence the warning by using preg_replace_callback() instead of "/e".

Test Plan: Sent myself a message with a bunch of multibyte UTF8 characters in it, it came through cleanly.

Use Celerity to version all static resources

Summary:
We don't use versioned URIs for images, so when they change users may get old versions.

This was a particular issue with the recent logo change, which several users reported cache-related issues from.

Instead, use Celerity to manage image URI versions in addition to CSS/JS.

This is complicated, because we need to rewrite image URIs inside of CSS, which means the hash of a CSS file has to be derived from the current image data. Otherwise, when we updated an image the CSS wouldn't update, so we wouldn't be any better off.

So basically we:

  - Find all the "raw" files, and put them into the map.
  - Find all the CSS/JS, perform content-altering transformations on it (i.e., not minification) based on the partial map, and then put it into the map based on transformed hashes.

(If we wanted, we could now do CSS variables or whatever for "free", more or less.)

Test Plan:
  - Regenerated celerity map, browsed site, verified images generated with versioned URIs.
  - Moved "blue" flag image over "green" flag image, regenerated map, verified "green" flag image and the associated CSS changed hashes.
  - Added transformation unit tests; ran unit tests.

Use head_key() and last_key() to explicitly communicate intent

Summary:
PHP arrays have an internal "current position" marker. (I think because foreach() wasn't introduced until PHP 4 and there was no way to get rid of it by then?)

A few functions affect the position of the marker, like reset(), end(), each(), next(), and prev(). A few functions read the position of the marker, like each(), next(), prev(), current() and key().

For the most part, no one uses any of this because foreach() is vastly easier and more natural. However, we sometimes want to select the first or last key from an array. Since key() returns the key //at the current position//, and you can't guarantee that no one will introduce some next() calls somewhere, the right way to do this is reset() + key(). This is cumbesome, so we introduced head_key() and last_key() (like head() and last()) in D2161.

Switch all the reset()/end() + key() (or omitted reset() since I was feeling like taking risks + key()) calls to head_key() or last_key().

Test Plan: Verified most of these by visiting the affected pages.
