Migrate all DB code to use PDO
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.
