[ansel] Feature Request

[Heath S. Hendrickson]

There are two things that I've been wanting in Ansel, but aren't sure 
how to add them myself.

1) Ability to delete all images in a gallery without deleting the gallery.
2) Overwrite vs. insert for images with the same filename in the same 
gallery.

I'll see if I can create the patches for #2, but I'm wary of doing #1 
myself as I'm just getting my hands dirty with PHP and it's a dangerous 
function.
