Limit parameter for [gallery] shortcode

[nboehr]

The gallery shortcode does not allow to limit the number of images displayed.

The attached patch adds this functionality. The default behaviour is not changed, i.e. by default, all images are displayed. The new parameter is called limit. Also, if you explicitly specifiy the IDs via include=, ids= or exclude=, all images are displayed, regardless of whether the parameter is specified or not. If you guys think that this behaviour is not optimal, please add your comments so I can adjust the patch.

Example usage:

[gallery id="57" limit=3]

The patch is against the latest HEAD revision 26993.

Seems like a good addition, +1.
