I improved the gallery scriblet in Scribo.
First of all, now it's really a Scriblet (subclass of Scriblet).
It's an ajaxified component, and when you open an image, it opens a nice
lightbox with the image in a bigger size in it.
There is also a separate view to edit the gallery: size of the gallery,
images, order of images, etc
See the attached screenshots, and tell me what you think :)
