* Renamed the hint window to TfpgHintWindow

* Moved F_Hint variable to fpgApplication.HintWindow property. TfpgApplication
  now manages the life of HintWindow.
* Moved DisplayHint (now called ActivateHint) and HideHint into TfpgApplication.
* Introduced a new TfpgApplication.HintPause property that will managed the 
  default delay before a help hint is displayed. Default is 1.5 seconds.
* gui_edit unit has been updated to handle the new changes.
* hintwindow example project has been updated to handle the new changes.
* TfpgHintWindow class now manages the Shadow Window (lifetime, size and 
  position).
* The Hint Shadow class is now moved to the Implementation section so it's not
  accessible to the world, but only via the standard Hint Window class.
* Introduced a HintWindowClass which is a global variable. It defaults to
  TfpgHintWindow, but allows the user to change it so a custom hint window
  can be used instead.
* TfpgLabel.Text is now of type TfpgString
