Issue: Last-info Incorrect if Contains Multi-Byte Characters

When the last update information for a content list item contains a multi-byte character (maybe only NULL bytes), the displayed last update is incorrect. In PHP 5.4, a Warning (error at offset) is shown. This is due to serialize() data being binary and not being stored in BLOB columns in the database.

Fixed in the next release by updating all columns that stored serialized data in BLOB columns. Already damaged last-info data will probably not be fixed by this change, but future updates should be handled properly.
