create make target for the about ubuntu page

<enrico> froud: it may be that we're talking about two different things. The
"About Ubuntu Page" is described here:
https://www.ubuntulinux.org/wiki/AboutUbuntuPage have a look
<enrico> froud: the text I've committed is what is currently displayed while
clicking on "About Ubuntu" in Ubuntu, not a chapter of a book
<froud> ok parts of this will be in the book
<froud> we need to integrate it and create a method by which to generate it
<froud> this will mean a mark target
<froud> essentially I envision just assembling pieces from the books to compile it
<enrico> sorry, what is a "mark target" ?
<froud> make target
<enrico> oh, yes, ok, I'm with you
<froud> we will still need a driver file
<enrico> it would be really neat to assemble it from other things. Also, I
would avoid having too many ubuntu descriptions around :)
<froud> yes there are already to many
<froud> in addition, we need to consider a balance in the description between
desktop and server
<enrico> oh, desktop and server could definitely share the same about ubuntu part
