Model animation events

• The model animations in Half-Life can have events attached to specific frames.
• Data-wise event is just a number with optional options string.
• In the game events are different effects played along with the model animation when it reaches the frame the event resides on.
• The events are handled and processed by the game logic. Entity implementations are responsible for handling the events, but there's a number of shared events, recognized by all monster entities.
