Name new location markers immediately

I though it would be be useful to be immediately prompted for a name when I added a new location marker.

It didn’t seem like such a tricky feature to add, so I had a go at implementing it.

I’ve already posted this as a feature request in Mantis, along with my patch ( but I thought I’d mention it here too.

Any chance this (or something like it) could be incorporated into 2.0-ongoing?
