Allow easy editing of IP address/hostname in static DHCP mappings

Currently to change a static reservation you have to delete the entry, then after the page reloads and the data has disappeared, re-add it. This usually means copying the MAC address into the clipboard, then re-typing the IP/hostname with the require changes. It'd be great if there was an Edit button or something, even if it just did the same as the Delete button but pre-populated the row of input boxes with the old values for tweaking/adding again.
