Message:

now uses new AutoLoadConverters instead of AutoloadConverterScripting. This doesn't inherit from ConvertBinaryFile, so these plugins all inherit from that again. Now we can initialise the converters, fix up the modifications to the arguments, before parsing them when we do new ConvertBinaryFile. PowerPointPlugin incomplete and still needs lots of work done for processing the result on open office conversion
