I added logging to notifyIME() in GeckoAppShell, and it looks like we get loads of notifyIME messages sent when dragging the handle. Each time we move the handle, we generate a click in the text field, so we probably want to suppress IME notifications while we're positioning the cursor.

We call restartInput on the InputMethodManager during each of the many notifyIME calls, and it tends to overwhelm the InputMethodManager. This patch coalesces the restartInput calls into 200ms bunches, so only one call is made within a 200ms period. I don't think delaying the call for 200ms would have big side effects, since the call is asynchronous anyways.
