places plugin: remote-server gtk bookmarks not opened

[Eli Collins]

In short, mintmenu won't open gtk bookmarks to remote systems if the bookmark has not already been mounted by gnome.

In detail...

Mint menu uses "xdg-open" to load any gtk bookmarks. This works fine for local bookmarks such as "file:///home/user/Documents", but doesn't work for gtk bookmarks pointing to remote systems, such as "sftp://user@server/". If the url has already been mounted by gnome as a network drive, xdg-open will work fine, but if the url has not been mounted, xdg-open (and the gnome command it calls, "gnome-open") will silently do nothing. (I'm betting this is a security feature, since xdg-open / gnome-open are used to load sometimes untrusted urls).

The only way I can see to fix this is to call "nautilus %s &" instead of "xdg-open %s &", since it has the correct behavior of auto-mounting remote bookmarks if needed. Other than that, it should behave in the exact same way as xdg-open.

Attached is a patch which uses nautilus instead of xdg-open for the gnome desktop only.
