Add sorting to gallery items

[AaronCampbell]

The idea is to integrate the functionality that my ​Reorder Gallery plugin offers into core as per ​Matt Mullenweg's suggestion over at my blog.

It should be rather easy, I'll try to get a patch up real soon. Hopefully Matt will stop by and let me know what version he'd like to integrate it into.

I uploaded the patch, works on my trunk install.

The 002 diff is to be used instead of 001. It's 001 with the missing entry in script-loader for gallery.js (aliased as "admin-gallery").

This adds an interface.js requirement. We're trying to eliminate interface requirements. Can jQuery UI be used instead?

I'm sure it could, it was set up to mimic wp-admin/js/widgets.js which does the widget sorting. I'll take a look at jQuery UI in the next day or two and convert it.

Yeah, widgets admin needs to be ported to jQuery UI. jQuery UI wasn't up to the task when 2.5 was released, but the latest jQuery UI beta might work.

To use the jquery ui sortables, we need the ui.sortable file (duh), but we also have to add the latest jquery.js from trunk. Should I ADD it (tag it as jquery125), or replace the current one with it?

Replace the current one.

My wikiformatting didn't work so great on that last post (left of a leading space before all my list items), so here it is:

Seems to be broken now. Error in FB:

sort.instance is undefined

Line 13

6988.004.diff fixes it for me. Seems they changed something in how it works.

Version in script-loader.php has to be bumped.

We should be extra careful about that in the future, because if Gears is in use, disabling the browser cache doesn't help.
