iseColumnSubType; obsolete some Enum values

To simplify and streamline code the following Enum values of iseColumnSubType have been obsoleted:

• Byte
• Now just uses iseColumnType.Byte to identify Byte columns.
• Integer
• Now just uses iseColumnType.Integer to identify Integer columns.
• NOTE: Integer is a database data type, which are 2 bytes - the equivalent of the Short (Int16) CLR data type. Within finPOWER Connect, database data type "Long" is equivalent to the Integer (Int32) CLR data type.
• Double
• Now just uses iseColumnType.Float to identify Double precision numeric columns.

The following iseColumnSubType values are still relevant:

• None
• Not applicable.
• Single
• Denotes a "Single" precision floating point number. This is not used in finPOWER Connect databases, but is still relevant when loading database schemas which may support this data type.
• Unicode
• Identifies the column as an NCHAR or NVARCHAR as opposed to CHAR or VARCHAR.
