- removed (linux incompatible) PngImage. In addition it was rather outdated (from 2003, newest version is from 2006)
- introduced UImage-unit for JPG/PNG/BMP image saving
- the png part uses the libpng12-0.dll (part of SDL_Image) so
- the jpg part uses either Delphi's Jpeg unit or FPC's base/pasjpeg unit
-> so no additional libs are needed.
