Json.net supports Bson however JValue convert every integer value to int64 bit..

In bson. int32 need 4 bytes and int64 need 8 bytes...so there is a room to improve it.

find JValue.cs

add a new constructor

public JValue(int value)
??????? : this(value, JTokenType.Integer)
??? { }

and then find

public override void WriteTo(JsonWriter writer, params JsonConverter[] converters)

add some codes here:

case JTokenType.Integer:

+?? if (this._value is int)
+????????????? {
+????????????????? writer.WriteValue(Convert.ToInt32(this._value, CultureInfo. InvariantCulture));
+????????????? }
+????????????? else
+????????????? {
+????????????????? writer.WriteValue(Convert.ToInt64(_value, CultureInfo.InvariantCulture));
+????????????? }

build it..it should work fine with bson from now on.
