This is an huge refactor to avoid handling Allegro FONT directly. Some changes: * Add she::System::defaultDisplay/Font, createRgbaSurface, loadSurface, and loadRgbaSurface. * Rename she::CreateSystem/Instance to she::create_system/instance. * Remove ui/font.cpp and move ui/fontbmp.cpp to she library. * ui::IButtonIcon uses she::Surface instead of BITMAP. * Rename she::LockedSurface::drawAlphaSurface -> drawRgbaSurface * Rename ui::SetDisplay -> set_display * Rename _ji_font_text_len -> ui::Graphics::measureUIStringLength
