Core/Player: Fix Restes/RaF exp on the exp bar and from kills.

Fixes a problem where when you kill a creature it will say you got RaF exp but you just got either rested or normal.

Also fixes a graphic bug where you never see your rested exp when you link with another player.
First thing, is m_rest_bonus > 10 a typo or intended behavior ? Not sure, sounds weird to me that 2 - 10 has no behavior listed.

Second, shouldn't rest and RAF be seperated, as both can apply ?
