hint window timer field variable renamed.

- Renamed the timer field variable from T_Chrono to FTimer.
- Renamed the OnTimer event handler from T_ChronoFini to HintTimerFired
- Disabled the timer *before* hinding the hint window. This prevents
  those add AV's that occur when you close an application.
- No need to explicityl disable the timer in HintWindow destructor.
  When you free a timer, it automatically gets disabled.
