I don't know if this is supposed to be this way ?

The `grunt css-themes` command now loops through all Sass files. There is no need to add the newly created file to the task list.

`<tbody/>` is automatically inserted, so we can guarantee that this affects all ths and tds in the last row of the table *body* and the head is left untouched

The alignment information were already in the generated html.
The css was the only thing missing, so I added it.
