added RTTI support for SynCrossPlatformJSON.pas unit
  *  now you can serialize published properties of any TObject as JSON (with TByteDynArray explicit support for blobs, and dedicated TList/TObjectList/TCollection process)
  *  introducing new TJSONTableObject class, able to manage ORM list results as returned by a mORMot server
  *  tested on VCL, FMX, FPC platforms - feedback is still wanted on all targets!
  *  we had to make some adjustment for the FPC RTTI, but sounds to work fine now, without the need of extended RTTI (so should work even with Kylix)
