Add SqlDataTable.ToList<T>() - Codable-style row mapping

Reflection-based mapper that matches column names to public settable
properties (case-insensitive), converting SqlValue to the correct CLR type.
Handles nullable types, bool, int, long, float, double, decimal, string,
DateTime, Guid, byte[]. Null SQL values leave the property at its default.

Also fix ToMarkdownTable to use AsString() instead of record ToString().
Bump to v1.2.4.
