calendar: show only when mouse clicks

[whooper2]

Is it possible to change the calendar widget behaviour to show only when the mouse clicks on top of it? Instead of just when it's hovering over.
If yes, how would this be achieved?

Fetch latest commit and disconnect mouse::enter signal from your widget like this:

yourwidget:disconnect_signal("mouse::enter", lain.widget.calendar.hover_on)
