Update admin/assets/css/admin-style.css

This one removes spacing glitch with "Backup Options" and "Restore Options".Tested on (firefox, opera, safari, ie8). Sorry for any inconvenience but I'm switching my own theme from custom build options framework to smof. I'm also developing google fonts previewer field but it's not ready yet so stay tuned :)
