[Feature Request] EventDelegate support parameter with reference

[yuewah]

In order to support parameter with reference, just modify EventDelegate.cs a bit

1.  [System.NonSerialized] ParameterInfo[] mParameterInfos;
2.  
3.  mParameterInfos = mMethod.GetParameters();
4.  
5. for (int i = 0, imax = mArgs.Length; i < imax;  ++i)
6. {
7.           if ( mParameterInfos[i].IsIn || mParameterInfos[i].IsOut )
8.           {
9.                mParameters[i].value = mArgs[i];
10.           }
11.           mArgs[i] = null;
12. }
13.
