Added arbiter service script for Windows and retired the coordinator one
Added profiler

Fixed test problems
Changes slightly the locking strategy of the StoreLocker so it works on windows too as expected

Instead of locking on the neostore we now grab locks only on store_lock file on windows. That allows

This also fixes a couple of failing tests on windows builds.
Oops. Fixes oversight that made test fail.
