- implements .bdf font loader based on convbdf (sure could have some clean up)

- adds three different font styles to the themes (normal, bold (default one), italic)
- implements code for specifing the font files in the theme config ('fontfile_normal','fontfile_bold' and 'fontfile_italic' in the 'extra' section)
- changes EditTextWidget to use the normal font (has some minor aligment problems with the caret now, though)
- extends the FontManager (new functions: getFontByName, assignFontToName, removeFontName)
- adds the font style constans to the builtin constants for the evaluator)
