Extra parameter to control the gallery type from the shortcode

[andrei-l-cristea]

Create a new parameter for the Modula Gallery shortcode that will allow you to control the gallery type, regardless of the gallery configuration.

For example you have a gallery that is set to Creative, and you are displaying this on a page. You then want to show the same gallery but as a slider on a different page, instead of creating a duplicate gallery you can just use an extra parameter, for example "show_as='slider'", and have the gallery type changed to slider instead of Creative.
