Move options into the engine

Browse Source 
Move the engine options into the engine class, also avoid duplicated
initializations after startup.  UCIEngine needs to register an add_listener to
listen to all option changes and print these.  Also avoid a double
initialization of the TT, which was the case with the old state.
