Blood pill/installer patches:Basic nearest neighbor 2x scaler for sprites (planed to add 2xSaI and SuperEagle in future).Support for per-model scaling using NetherScript for legacy models (to support normal and 2x sprites).Added PK3 generator in testinstallationscript.bat (need to supply winrarexe to get working). Note that PK3 works a WAY faster than unpacked files novadays, because HDD is slower than CPU zip decoder.- several other fixesrerun testinstallationscript.bat
