- ucs4_to_qchar() and qchar_to_ucs4() have been inlined.
- ucs4_to_qstring(): pass a QString to avoid a copy.

Basically, I replaced all methods in the font_metrics namespace by a proper virtual interface FontMetrics. The FontLoader is _the_ container for FontMetrics.
This patch should also bring some optimizations in a number of place in the code. This is because we do not need any more to search for the LyXFont at each font_metrics call. In effect, the speed advantage is not as sensible and this is a bit deceiving considering that this was my primary motivation behind the patch. But I like the patch anyway as it cleans up the relation and interfacing between fonts, metrics and frontends.
* frontends/FontMetrics.h: new virtual interface. Renamed from font_metrics.h
* qt4/GuiFontMetrics: corresponding qt4 implememtation. Renamed from qfont_metrics.C. The smallCaps particular case treatment has been transfered here as well as the width cache for MacOSX and Windows.
* qt4/QLPainter.C: the smallCapsText has been reworked to return the width of the drawn text.C
all other files: replace font_metric helper function call with corresponding FontMetrics method calls.
