(1) Added subroutine taskadmin to serve as "lio's main".

     (2) Retouching lio_init; together with a different version
         of a "lio_finalize" (to be renamed probably) these should
         be called to start and end the program and, together with
         taskadmin, will probably be the only subroutines to be called
         directly by the program using liolib. Initialization of
         variables that change in each call to the program whould
         be dealt with inside the taskadmin; lio_init and "lio_finalize"
         (not the existing one, the planned one) should be called only once.

     (3) Moved "mods" to "liomods" and started a mod for keywords
         (liokwrds). This way "mods" is free to be used a folder
         to store the .mod files (insted of just leaving them in
         the main directory).
