Remove --default-device-scale-factor

Remove --default-device-scale-factor because chrome now gets scale factor from device.
Add --force-device-scale-factor instead to override it.
Remove obsolete comment in resource bundle.

Rick, Rob, can one of you review this first?

http://codereview.chromium.org/10546158/diff/2001/ui/aura/monitor_manager.cc
File ui/aura/monitor_manager.cc (right):

http://codereview.chromium.org/10546158/diff/2001/ui/aura/monitor_manager.cc#...
ui/aura/monitor_manager.cc:35: float scale = 1.0f;
this value will be ignored if --force-device-scale-factor is specified.

Thanks Oshima.  
Please update about_flags.cc too - it still references
--default-device-scale-factor

http://codereview.chromium.org/10546158/diff/2001/ui/aura/monitor_manager.h
File ui/aura/monitor_manager.h (right):

http://codereview.chromium.org/10546158/diff/2001/ui/aura/monitor_manager.h#n...
ui/aura/monitor_manager.h:46: // or |gfx::Display::GetForcedDeviceScaleFactor()|
will be used if omitted.
Update this comment to say it's overridden (not just "used if omitted").

And chromeos/login/login_utils.cc too, I believe.
