Replace all occurrences of "<?php echo" and "<?php print" by "<?=" to
reduce noise in templates.

Note that as of PHP 5.4.0, "<?=" is always available and no longer
requires "short_open_tag" to be set.

All DB code currently uses the quickly aging mysql_* functions. These
functions are strongly discouraged and may eventually be deprecated.

Transition all code to utilize the PDO data access abstraction layer. PDO
allows for consistent query code across multiple databases. This could
potentially allow for someone to use a database other than MySQL with
minimal code changes.

All functions and behaviors are reproduced as faithfully as possible with
PDO equivalents and some changes in code.

XHTML should be eliminated from lib/ as much as possible. This pulls the XHTML
out of a function that simply echoes the code, and moves it into a more
reasonable template file in account_search_results.php
