Support wider range of TT fonts

[Warren_Baird at cimmetry.com]

ChangeLog:

     WineEngCreateFontInstance now support more truetype fonts.

Description:

     The problem was related to the font 'fsCsb[0]' flags.
     Those flags tell which charsets are supported by the font.
     For many (old) fonts, those flags are not set (all zeros)...
     So we should treat 'fsCsb[0] == 0' as a "wildcard" (accept all charsets).

     Moreover, only truetype fonts having a 'ft_encoding_unicode' encoding were
     working. All others 'charmap' were left NULL after calling OpenFontFile.
     Now, if 'charmap' is still null, we try to use the 'ft_encoding_symbol'
     and in the last resort, 'ft_encoding_apple_roman'.
