* Check for module initialization failure (extremely rare)

* The MySQL FIELD_TYPE converter can now be a sequence of 2-tuples.
   Item 0 is a bit mask (using FLAG.*) which must be matched. This should
   be an integer. Item 1 is the conversion function. If item 0 is not an
   integer, then this function is considered the default converter for
   this FIELD_TYPE. Note that these tuples are considered when the query
   has been executed and the result is available, so it doesn't add a
   per-row overhead.

 * As a result of the above, BINARY BLOB fields are now returned as
   character arrays using the array.array class. Non-BINARY BLOB fields
   (i.e. TEXT) are returned as strings. If unicode is enabled, they are
   returned as unicode strings.

 * Bump version to 0.9.3b3.
