commit 3245a5383b813f281bb19ec768519dedf13447b0
Author: Damian Johnson <atagar at torproject.org>

Replace curses text format attributes
Bit by bit we're removing direct curses usage, and someday there won't be an
'import curses' line left outside our new nyx.curses module.
For now though settling for our text format attributes. We already had enums
for the colors and now we set text attributes (bold, underline, etc) the same
way. This is a pretty big overhaul so no surprise if there's a regression here
or there but gotta bite the bullet at some point. :)
