(Frodo) Psiconv program update
  * Created html4 target
  * Update of xhtml target (print entities if ASCII, and others)
  * Made everything static that should not be exported
  * Renamed stuff to xhtml were appropriate
  * The fileformat data does now contain the supported Psion files to convert
  * This is also printed in the help text
  * ENCODING_ASCII_HTML introduced (only used internally)
  * Replaced debug, silent, verbose options with noise option
  * Default targets are XHTML and TIFF
