As reported in #451, with the Mac server, sleeping and resuming (on the
server) causes the mouse speed to double on the client upon resume.

Fix by removing the CFRunLoopSource from the run loop on screen disable
before releasing it. CFRunLoopAddSource in enable() retains the
CFRunLoopSource, so even though the source is released in disable(), the
run loop still has a copy. When the server comes out of sleep and the
screen is enable()'d, another event tap and run loop source are created
and added to the run loop, so the callback is now being called twice for
every mouse movement, and so on for every additional time the server
sleeps.

This is a better approach than the fix in 267f3ac, because although
that fixes the issue by disabling the event tap before the event tap and
run loop source are released, a memory leak still occurs since they are
retained by the run loop.

Ensure that we actually kill the server if we go from screen saver desk to real
desk.

… screen saver activates

When it is restarted, and screen saver is active, the clipboard no longer works
correctly.

The desk swap detection routine just below does not work properly when the
desktop goes from screensaver back to normal. If it did, probably this
workaround would not be needed.
