[gutsy help] Nautilus extensions

There is mentioned source for the Nautilus scipts in the help chapter 6.13.1, but it is not mentioned how and where to get Nautilus extensions in the chapter 6.13.2. This is confusing as the Google gives mostly result from the Gnome help without pointing to the fact that one has to install extensions via Synaptic.

Proposals:
a - easy) Adjust the help and write in the chapter 6.13.2 that extensions are available via package manager.

b - difficult) Create the Nautilus extension management tool within the Preferences dialog of Nautilus (in the similar way the Firefox has the Addin manager).
