sort() and sort_multipv() are almost the same, so
use only one implementation.
Also introduce the natural RootMove::operator<() to
compare the moves instead of compare_root_moves(),
this will allow to use std::sort instead of our
home grown bubble-sort.

Moves are already sorted, so just consider the best
and the second one.
Some trailing whitespace remove noise crept in due
to my editor removes it before to save.

After testing and comparing output with standard Glaurung
a couple of issues arised.
A default value was wrong and init_uci_options() missed a couple
of stringify() calls. Also storing bool values as "false" and "true"
needs some care.

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.
