Removed NSScreen member of OS X monitor.

Browse Source 
Apple's documentation of [NSScreen screens] mentions that, "The
(screens) array should not be cached.  Screens can be added, removed,
or dynamically reconfigured at any time."  Because of this, we simply
obtain the screen from a displayID whenever we need it.

Fixes #492.
Closes #493.
