Updated setup.ini with descriptions, categories, and dependencies

[Charles Wilson]

I just committed a change to cinstall/temp/setup.ini to reflect the 
recent splitup of the ncurses package.  Bascially, all dependencies on 
'ncurses' were changed to 'libncurses5 terminfo'.  I also added entries 
for libncurses5, libncurses6, and terminfo.

Of course, the latest vim package now depends on libncurses6 -- but I 
didn't change that.  temp/setup.ini's vim entry is still 6.0-1, which 
depends on libncurses5 so I did not adjust that entry further.  I'll 
leave that to Corinna.

(BTW, is cinstall/temp still active, or did I just waste 10 minutes?)
