Correcty resey TB hit counter

Browse Source 
Restore original behaviour to reset
the counter before a new move search.

Also fixed some warnings and added const
qualifier to a couple of functions, as
suggested by m_stembera.

Thanks to Werner Bergmans for reporting
the regression.

No functional change.
