[FFe/UIFe] Fixing bug 713423: Unity launcher gets cluttered when having multiple partitions and/or external volumes attached

[Andrea Azzarone]

Hi all,

We have a change in trunk which changed the way Unity handles file system icons.

Copy pasted from bug report #713426:

1) It should be possible to remove specific file system icons from the
Launcher by un-checking the “Unlock from Launcher” option (or dragging
to the trash).

2) In the case of non-removable file systems, the system should
remember these settings so that rebooting will not return these icons
to the Launcher.

3) In the case of removable file systems (USB keys, SD cards, etc...),
if a removable file system is removed and then re-attached it should
re-appear in the Launcher. If the removable file system is not removed
and the user has removed it's icon from the Launcher, the icon should
not return to the Launcher even if the computer is re-booted.

4) All 'specific file system' icons that the user has removed from the
Launcher should be displayed in the Dash file Lens in the “Favourite
Folders/Folders” category. This allows the user to re-add these icons
to the Launcher at a later date.

Also we removed the ccsm option "Device Options".

Cheers,

Andrea
