Move closing of file in Book destructor. This
guarantees us against leaving the file open under
any case and simplifies also Book use.

We currently fail on an option with a sapece in the name,
as example
setoption name Clear Hash
returns error message "Option Clear not found". This
patch fixes this off-by-one type bug.
Thanks to Joona for spotting this.

There was one occurence when the StateInfo variable went
out of scope before the corresponding Position object.
This yelds to a crash. Bug was not hit before because occurs
only when using an UCI interface and not the usual benchmark.
The fix consists in copying internally the content of the
about to stale StateInfo.

We don't backup anymore but use the renamed StateInfo
argument passed in do_move() to store the new position
state when doing a move.
Backup is now just revert to previous StateInfo that we know
because we store a pointer to it.
Note that now backing store is up to the caller, Position is
stateless in that regard, state is accessed through a pointer.
This patch will let us remove all the backup/restore copying,
just a pointer switch is now necessary.
Note that do_null_move() still uses StateInfo as backup.
No functional change.

This patch modifies think() signature to accept
also opponent time. This is needed for future
changes to time managment.
Still no functional change.

Instead of old-style C string functions use standard
library to greatly streamline the implementation.
No functional change.

Class UCIInputParser is now a typedef of a std::istringstream,
this greatly simplifies the code, especially the many conversions
from string to integer are now handled automatically by the
stream instead of relying on a chunk of C-style atoi() calls.
