-Renamed HashMap functions to follow coding style.
Only begin, end, find, and variants are left lowercase, in keeping with C++ algorithm and range-based for support.
-Fixed some accounting issues with list and forwardlist; size wasn't properly being maintained.
-Made a small pedantic change to ThreadManager to ensure that m_numThreadsSynced got reset to 0 before the NotifyAll() to eliminate the miniscule potential for deadlock it would cause if it happened after another thread had already woken up.
