Validation functions; IsValidUri() function added

• finBL.Runtime.Validation.IsValidUri(URI, Message, Scheme, AllowBlank)
• URI is the URI you want to check, e.g. "https://www.intersoft.co.nz"
• Message returns the error message if the validation fails
• Scheme is an optional ByRef parameter that will return the Uri scheme if provided
• e.g. "http", "https", "ftp"
• If AllowBlank is True then the function will return True if URI is blank
• Optional parameter; defaults to False
