Utilities.Core:  Added CaseInsensitiveStringComparer class.  Utilities.Sql: Removed code relating to the INameable interface, and code in the Server class for relevant and ignored database collections.
Utilities.Sql: Refactored classes in SqlServerDatabase.cs so each class has a reference to the instance that owns it.  Removed superfluous properties that can now be calculated due to the refactoring.  Added methods for use in creating T-SQL MERGE statements.
