IMPLEMENTED for v5.9.92

Implement 'book *' commands. Only 'book add' was implemented at the moment.
book
Implemented by extending the protocol messages between frontend and 
adapter. Engine book options uncontrollable, since I am more reluctant to
modify the protocol between adapter and engine (UCI), but it could be done.

Some defaults were wrong, e.g. hard mode at startup.

Set writing to adapter.log to false by default.

Some command-line options didn't work.
--post
--easy
--manual

All pieces of text doc transformed into texinfo.

Command 'hash on/off'
UseTrans to be variable and driven by new option.

Command 'null on/off'
UCI option NullMove Pruning

Command memory
UCI option UseTrans

Command memory N
UCI option Hash

Commands hashsize/hashsize N
Removed, since slots are meaningless

Option --memory didn't work.

gnuchessx

gnuchessu

Default config so that the config file is not mandatory.
