Subject: Added Windows Impl for ScreenMode and rotation change; Windows
 Fullscreen Hint

Added windows implemenation for screen mode change lifecycle and screen rotation
screen modes.
+++++++++++
Added getHighestAvailableRate() to Screen mode as a helper function
which loops over the available rates of this screen mode and returns the
highest available.

Added toString impl to ScreenMode.

+++++++++++
Unit Tests: TestScreenMode01NEWT,TestScreenMode02NEWT are modified adding the gears as GL
event listeners.

+++++++++++
Notes:
1- Screen modes with bits per pixel values not same as current are currently filtered out.
2- Since windows stores the Display settings differently you will see some duplicate values
which the documentation says is usual. These modes are not filtered out in getScreenModes().
Keeping values same as provided from windows enum.
3- BitsPerPixel is currently natively read on windows only.
