Fixed a Bug in the superobject.pas Library

That's a Delphi library for reading and modifying JSON objects. It is used in Google Calendar, Google Drive, Google Contacts, Google Tasks and Dropbox Delphi components. This fix deals with the bug that could have caused random access violation errors for 64-bit applications.

The updated version of superobject.pas is included in the trial versions of the above-mentioned components.

We would like to thank our user Carlo S. for bringing this issue to our attention.
