If the terminfo entry has colors#256, assume that setaf and setab work

Browse Source 
and use them for the 256 colour set. If the terminfo entry doesn't have
colors#256 and the user gives -2 to the client, use a \033[38;5;Xm
sequence as before. Should allow fbterm to work with it's weird setaf
and setab.
