Version Bump

From the Changelog:
3.30  2014-01-31T21:10:54Z
     - Removed markup from preformatted text in the `pg_prove` documentation.
     - Updated copyright dates.
     - Added note to the docs mentioning that `pg_prove`-specific options are
       not supported in `.proverc`, unfortunately.
     - Removed `ON_ERROR_ROLLBACK=1`, as it does not work well with scripts,
       anyway.
     - Removed the Pod tests from the distribution.
