(1) Taskadmin renamed as liomain; since it is going to be called
      directly by outside programs like amber, it might as well have
      the name of the program in it.

  (2) Liomain is called by both liosolo and SCF_in, but still does
      nothing (it is empty of commands). The idea would be to
      eventually replace SCF_in by liomain and another interface
      subroutine that passes the information from amber to lio
      (liosolo would be doing the information gathering but from
      input files instead of "translating" amber data, and then
      it would call liomain).
