Add collection count validation in NetDataReaderExtension

[Riryan]

Added validation for collection count in GetArrayExtension, GetArrayObject, and GetList methods. Introduced a constant to limit maximum collection size.

This appears to remove:

          ///Read a quantized Vector3 from the reader, the vector is quantized into integers based on the cell size and compression mode, which determines how many bits are used for each component.
        public static Vector3 GetQuantizedVector3(this NetDataReader reader, ushort cellSize, out int compressionMode)
        {

Is this intentional? Also please pull request against develop.

On MmoKitCE, you should be able to switch to develop branch. Let me know if this is not the case.
