Fixed A-Z ordering

Hello my friend.
I found a bug in the way your plugin is reordering the names of the sites: it is not considering upper/lower case. So it is ordering names like this:

Site A
Site C
site B
site D

To fix this, I modified line 25 and now looks like this:

$blog_names[$site_id] = strtoupper($site->blogname);

and it did the trick:

Site A
site B
Site C
site D

Hope you can merge it to a new update.
Thanks!
