Update v2.9.2 with responsive design

I'm glad to anounce that, from now (v2.9.2), EVO frontpage module has a responsive design, which means that users who visit your page from devices with a small screen or resolution, will see EVO frontpage in a special way, as it will adapt its size to be more user-friendly, changing the number of displayed columns (for example, if you have 3), to only one unique column.

In addition, some minor changes has been done in the module source code, as well as some changes on the CSS styles to be a little more customizable.
