Update "5 Latest Moderator Actions" no results message

In MyBB 1.6, we show "Sorry, there were no results found with the criteria you selected." in the Mod CP when there aren't any moderator logs in the database. This makes it sound like the moderator has performed an action when they haven't. To make it sound more friendly and understandable, I've added a new language string and template which displays "No moderator actions are currently logged." instead.

Use `text-overflow: ellipsis` for session IP address

Due to the recent addition of IPv6 support the IP addresses of the administrators logged in will jump to a new line if they're using IPv6. To make this a little neater I've added `text-overflow: ellipsis` to the desktop and mobile classes, and given the <li> a title with the full IP address.
