I don't understand part of these two commits.

1) moving the QuickStart and Visual Guide .desktop files from tdebase to 
tdeaddons, but leaving the main docbook in tdebase.
IMO moving the two docbooks to tdeaddons is incorrect. Users may choose 
to install tdebase but not tdeaddons and in such situation (although 
unlikely, I concede) both guides would not be available.
QuickStart and Visual Guide are basic entry points for new users, so I 
think we should put them back where they were before (i.e. in tdebase).

2) I don't see the logic of having an option BUILD_TUTORIALS to disable 
building the tutorials until they have been updated. What about most of 
the help handbook so? If we follow the same logic, we should disable 
most of them as well. I propose we remove the option and just build the 
tutorials, even in incompleted/not fully updated.

Cheers
