Added data-attribute no-expander to <columns> to disable the .expander

[ghost]

Added data-attribute no-expander to to disable the .expander.

Reason of adding:
To disable adding th.expander on a column when it has 12 size.
It breaks the full width images in the emails in MS outlook & MS live, setting the width of the cell 50%.

With this edit, you can disable the expander, by adding no-expander to
Example:
<columns large="12" small="12" no-expander>One</columns>
Results in:
`

One

We talked about doing something like this. Like the way you made it an attribute. Can you share a code example use case we can test against to make sure this PR solves it?

This is the mail we made. (all names of the company cleared.) On windows outlook (live) mail the images went to 50%;

With the addition:

Then it worked for 100% wide.
