pull request 229/#H9299 - DECgraphics for curses

Browse Source 
Fixes #230

Incorporate github pull request #230, support for DECgraphics-style
line drawing in the curses interface.  I've rewritten the
curses_convert_glyph() part so that it doesn't require C99 and
doesn't reinitialize its pair of arrays for every character written
to the map.  The DECgraphics conversion is now a straight char for
char one, DEC line drawing code to ACS, without regard to what map
symbol is intended or what 'cursesgraphics' uses for that symbol.
