ehouse 8f08667f5d Lots more changes, and some reversions. Win32, gtk and ncurses all 
work now including saving/opening games.  Network play probably
doesn't as writing/reading a dict from stream has to change.  It's
doubtful patches from this branch will be merged.  Rather, I'll take
the concepts and crib some code when re-implementing.  Concepts:
XP_UCHAR becomes UTF-8 on both platforms, and on wince we translate to
wchar_t just as now but from the utf-8 codepage.  That keeps the work
and risk to a minimum.
