Use V_memset instead of memset.
Add ugly hack/workaround to fix ENTITY_CHANGE_NONE spam. Add SPROP_ENCODED_AGAINST_TICKCOUNT to most props. It's spamming these messages because in minimal table mode the unit suppresses the state change to once per 0.4s. Afaik adding this should have no side effects because m_fSimulationTime has the same flag, so it's using this mode anyway.
