Character: Incapsulate m_MoveRestrictions and m_Core

Browse source 
Instead of leaking the m_MoveRestrictions to all classes which needs to
adjust the Character velocity, add a setter which takes into account those
restrictions.

The shotgun bug replication requires an access to the Velocity without the
restrictions applied (so we have to have this dirty setter).

Expose only *const* CCharacterCore to force the setters usage and prevent
incorrect write.
