Further changes: -- A more synthetical organisation was chosen. Indeed, Lilliput-II only need encryption and Lilliput-I need encryption and decryption, so LilliputTBCencrypt is always used for lilliput-I and LilliputTBCencryptdecrypt for Lilliput-II. And LilliputTBCdecrypt is no longer described because no version uses it. +- A simpler file organization was chosen.
