Themed Bake template

[ravage84]

It would be nice, if this plugin provided a bake theme.

https://book.cakephp.org/bake/1.x/en/development.html#creating-a-bake-theme

Instead of php bin/cake.php bake fixture ModelName one could execute php bin/cake.php bake fixture ModelName --theme fixturize.

PR is welcome.
