1.1.0

• Fixed GetMapNodeDistanceFromPoint and GetClosestMapNodeToPoint.
• Some refactoring.
• New natives:

native GetAngleBetweenMapNodes(MapNode:first, MapNode:second, &Float:angle);
native GetMapNodeAngleFromPoint(MapNode:nodeid, Float:x, Float:y, &Float:angle);
native GetMapNodeConnectionCount(MapNode:nodeid, &count);
native GetHighestMapNodeID();
native GetRandomMapNode(&MapNode:nodeid);
