Enhancement: Refactor the Table-Based Calls to return IEnumerable<ExpandoObject> instead of IEnumerable<dynamics>.

[mikependon]

Currently, the result set of the following methods is of type IEnumerable<dynamic>. To be more specific and direct, it is good to return the type of IEnumerable<ExpandoObject>; instead.

using (var connection = new SqlConnection(connectionString))
{
	var person = connection.QueryAll("Person");
}

In which you can as well inferred it like this.

using (var connection = new SqlConnection(connectionString))
{
	var person = connection.QueryAll<ExpandoObject>("Person");
}

Or even via IDictionary<string, object> object.

using (var connection = new SqlConnection(connectionString))
{
	var person = connection.QueryAll<IDictionary<string, object>>("Person");
}

Impact: There should be 0 impact on the existing code of the consumers.
