Now we set the default localized font to the "text_default" font of the
currently active theme and default to the big GUI font in case none is
specified properly.
This makes it easy to get a localized font for the current
TranslationManager charset if one has been loaded. It tries
first to find one for the BigGUI or GUI fonts and then looks
for any acceptable font.
Also only use lower case font name for the FontManager HashMap.
This is to avoid issues with the case when looking for a font by
its name. There was for example an issue for font helvB12 that is
named helvb12 in the scummmodern theme.
OSD is now using the kGUIFont instead. The main advantage is that
the kGUIFont can be used for translated text while only ASCII
characters were present in ScummFont.
- 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)
