Plugin version is not correctly reported in information_schema

[shinguz]

The version of the PBXT plugin 1.1 is not correctly reported in MySQL information_schema:

SELECT plugin_name, plugin_version, plugin_type_version
  FROM INFORMATION_SCHEMA.plugins
 WHERE plugin_name IN ('PBXT', 'InnoDB');

+-------------+----------------+---------------------+
| PLUGIN_NAME | PLUGIN_VERSION | PLUGIN_TYPE_VERSION |
+-------------+----------------+---------------------+
| PBXT | 0.1 | 50153.0 |
| InnoDB | 1.0 | 50153.0 |
...
| InnoDB | 1.1 | 50507.0 |
+-------------+----------------+---------------------+

I expect a version number like 1.1 or even 1.1.01 the same way as InnoDB plugin does.
