Don't clear EasyMove in search() EasyMove is cleared after every iteration of the search if the 3rd move in the PV of the main thread changes from the previous iteration. Therefore, clearing EasyMove during a search iteration may be excessive. The tests show that this is indeed unnecessary. In the new version the EasyMove variable is used only in the Thread::search function.
