dimok321 6d6f0f2243 *Added a widescreen factor to the settings which defines how much the images should be scaled down in X-Axis to look like widescreen. This value is usually 640/854=0.75 but might be not "looking good" for some people, so it is a setting now. It is applied to covers/buttons/windows (on set widescreen prompts)/several images
*Added a font scale factor to the settings. This font scale resizes the overall font sizes. Only full integer font sizes are supported. The font scale factor is multiplied to the font size of a text and the result is rounded and used as the font size. It's a good quick fix for too big fonts.
*Fixed GAMEID_GAMETITLE folder game layout
