Guest name when adding topic/post via external script

[The Krotek]

I've tried to create a topic/post from guest with certain display name, but it seems, that right now it's not possible since setAuthor($member) function accepts only member's ID, and if it is empty or zero nothing displays. At the end you'll have ** as topic/post author, where asterisks are just enclosure to empty name. So I'd like to suggest you to add an extra check like this:

If $member is not integer - use $member value as guest name.

For example, I can use setAuthor("GuestDude") and it'll display *GuestDude* as topic/post author. Very simple and can save a bunch of time for those, who want to use names for guests when posting via external script.
