yeah, setupterm() makes no sense if urwid is run with the html_fragment
or web_display modules.  Maybe this code could be put in the new base
class of curses_display.Screen and raw_display.Screen
"RealTerminal" (process_keyqueue should probably be moved there too.)
Or it could go in curses_display and eventually some other way of
getting that information could be used for raw_display.

Also, you need to handle the case where "import curses" fails.

It's a good start though :-)
