QLineEdit: disable cursor blinking on hide

Browse Source 
QLineEdit activates the blinking cursor timer when it's shown,
but never deactivates it, resulting in constant wakeups even for
hidden line edits.

Note that this is a workaround. Qt is supposed to send a focus out
event to line edits that get hidden. In some corner cases, it
doesn't, and only a hide event is sent.
