Malte Weiß, 09.04.2003: - A folder is specified by user to locate all font files.
                        - CybFontManagerC is now responsible for the entire font metric.
                          GetTextSize uses external .MET files (created by 'FontMetric') to
                          determine the size of each glyph.
                        - Added some helper functions (GetFontName, GetFontFilename etc.).
            10.04.2003: - GetFontMetric is now responsible for loading metrics.
