Up to now, the TSQLRecord.ID property was defined in mORMot.pas as a plain PtrInt/NativeInt (i.e. Integer under Win32), since it was type-cast as pointer for TSQLRecord published properties.
We introduced a new TID type, so that the ORM primary key would now be defined as Int64.

All the framework ORM process relies on the TSQLRecord class.
This abstract TSQLRecord class features a lot of built-in methods, convenient to do most of the ORM process in a generic way, at record level.

It first defines a primary key field, defined as ID: TID, i.e. as Int64 in mORMot.pas:

type
  TID = type Int64;
  ...
  TSQLRecord = class(TObject)
  ...
    property ID: TID read GetID write fID;
  ...

In fact, our ORM relies now on a Int64 primary key, matching the SQLite3 ID/RowID primary key.
This primary key will be used as RESTful resource identifier, for all CRUD operations.
