-plugin videos now need to be in subfolders if you have "coverFolder" for the ini set

Browse Source 
-plugins now also play videos which have the magic number as name if no specific video was found
-switched from libjpeg to the turbojpeg wrapper from libjpeg-turbo to simplify the whole jpeg decoding code by alot
-heavly optimized the video decoding code
