- If fonts are specified as xlfd, convert to fc names before creating them.

This was we internally only deal with fc names and properties. It will
  incur a small performance hit as the font needs to be parsed/unparsed,
  but this is only for backward-compatibility to support old xlfd names.
  People are encouraged to swtich to fontconfig names.
- WINGs no longer adds sans as a fallback for internal fonts. It is
  automatically done by fontconfig (if it can't find the requested font
  it will use the closest match which is the default font: sans-serif)
- Added code to honor the AntialiasesText global option
- Fixed style names for WMCopyFontWithStyle()
- Added fonts in style files where they were missing. Also changed some
  fonts to better defaults.
