If NEWT_MONO does not exist, SLtt_Use_Ansi_Colors should still equal 1

The monochrome terminal change in libnewt forces color terminals to monochrome
anyway. The following patch to newt.c sets SLtt_Use_Ansi_Colors to 1 if
NEWT_MONO does not exist.

My understanding is that if you want to use newt in monochrome mode, you'll need
to set the NEWT_MONO environment variable. If it doesn't exist, we get color.
With the above patch you are forcing newt to use color mode even on monochrome
terminals. That's exactly the bug that was fixed in the latest newt. Slang sets
SLtt_Use_Ansi_Colors to 1, but only if the terminal supports colors (in terminfo
It's possible to force color mode with slang's variable COLORTERM.
