Cocoa: Hide cursor instead of using blank image

Browse Source 
When cursor isn't in normal mode and should be hidden, use [NSCursor hide]
method instead of setting it to blank image. This should prevent
situations when hidden cursor becomes visible after system notification
was shown.

Fixes #971.
Closes #1028.
