Make bookmark_utils::GetNameForURL return a string16.

Make bookmark_utils::GetNameForURL return a string16.

It is returning Unicode so it should be a string16.
The callers want a string16 anyway.

I'm considering moving this function into the _gtk file, since it's only used by
gtk.  What do you think?

seems ok to move it, but what do the other platforms do?

I guess on Windows it might use the os_exchange one.  On Mac, who knows!

I think I should submit this change regardless of code location.  LGTY?

[Evan Stade, 2011-01-21 00:56:47]

ok, move away. LGTM either way.
