Fixed #4455 (redundantCopy when precleaning with memset)
astyle formatting
add VS2012 projects for my personal use (using /LTCG, /MP, /RELEASE, /MT)
move astyle options to astyle.ini and use it in runastyle and runastyle.bat
astyle.ini: use --lineend=windows since when having autocrlf=true using --lineend=linux messes up the line endings
gui: losslessly compress images with https://github.com/subzey/zopfli-png
update tinyxml2 to d0a38c3a206fe6efba605ff60e82683e64eccf89
