First this bug is depencent on bug 73937 being fixed first so that symlinks
work correctly.

Using symlinks instead of removable media for nautilus would have numerous
benefits. 

1) on multi user systems, most users typically only have access to their
home dir. So using .dekstop files to link to /mnt/cdrom just seems kind of
weird, since it kills the user spacial reference that everything they need
or can do work on is in their home dir.

2) when using home dir as the desktop, you get a great spacial reference,
since everything the user needs is in their home dir ($home/cdrom etc.)

3) makes these mount point easily accessible from the terminal. Right now
if i go into my terminal and do dir or ls i get see cdrom.desktop, except
these are worthless in the terminal since the shell can't use .desktop
files. If symlinks were used i could do cd ~/cdrom. this would do alot to
unit the spacial use of $home as the desktop and $home in the terminal.
