add XFT support and make UTF-8 support configurable

This patch includes many changes:
- moved font and printing functions to XUtil.hs and created an
  abstraction layer to font management;
- ported the core, StdinReader and PipeReader to the new font
  management system.

To enable UTF-8 support configure with the "with_utf8" flag (requires
utf8-string):
runhaskell Setup.lhs configure --flags
