Support SHOW CREATE TABLE

[adamziel]

WordPress/playground-tools#154 introduces a "clone my site in WordPress Playground" feature. A part of it is dumping the entire database into an SQL file and then running the file in a WordPress Playground instance.

At the moment, it's broken because the SHOW CREATE TABLE query isn't supported yet and yields an error:

MySQL query:

SHOW CREATE TABLE `_mysql_data_types_cache`

Queries made or created this session were:

Executing: BEGIN | (no parameters)
Executing: ROLLBACK | (no parameters)
Error occurred at line 3378 in Function handle_error. Error message was: Unknown show type: CREATE TABLE.
