(Frodo) Make the formats stuff work again

  * Amend the configure.in to select the right targets
  * Remove RTF support (it never worked anyway)
  * Update the links creation scripts

And in the psiconv program and library:
  * Some fixes to reduce compiler warnings
  * Emit tabs as spaces in the HTML4/XHTML generators
