[Hover] Fixed the delaying of hover dismiss on continuous mouse clicks
[Hover] Fixed the delaying of hover dismiss on continuous mouse clicks

Summary:
When continous mouse clicks happen hover emits the hide signals continously
to edje. As the embryo program for hiding requires some time to finish the
animation, if within that time another mouse click comes the program gets
invoked again and thus the hiding will get delayed till the mouse clicks ends.
This patch fix that issue by adding a flag for emitting signals.
