adding opera buttons for dragonfly and cache reload

Opera has some great features buried in its menus, so I make a couple of buttons to add them to the standard toolbars.

The first one I use is Reload From Cache, which does exactly what it says. It reloads the page entirely from cache, which is really useful when you combine it with the ability to view source in your choice of text editor. You can view source, make some test changes, reload from cache and see if it worked. It's less twitchy than inline editing since it only reloads when you're ready; and it's far less aggravating than trying to do serious edits in a tiny window with no syntax highlighting.

The second is bleeding obvious - a button on your toolbar to load Dragonfly. I'm sure they'll add one as standard once it's out of beta, but who's that patient? :)

So anyway, here are the buttons. Click the links and they'll get added to your custom buttons; then you can drag them onto whichever toolbar you like.
