On some of these systems, when the javafx toolkit initialises the native hardware cursor, it produces artefacts which can be seen on screen (in the framebuffer for example). This change adds a system property "monocle.cursor.enabled" that can disable the creation of a native cursor in each of the Monocle NativePlatform implementations in favour of a NullCursor which is a no-op implementation of the NativeCursor abstract class that all native cursors have to implement.
> NullCursor class already existed and was being returned for some implementations like AndroidPlatform and HeadlessPlatform. This change builds upon that and conditionally returns NullCursor for all platforms.
> A system property "monocle.debugcursor" has also been added to turn on logging of which NativeCursor has been selected when the toolkit initialises.
