Calendar zoom in/out button to show more days

Button to zoom in/out on the weekly and monthly view.

It would show more days.

The selected view (zoom in %) would be saved for the next time we load the weekly or the monthly calendar.

The best thing would be to add a zoom button and also the ability to ctrl+mouse roll for zooming in/out as currently the mouse roll isn't showing more days.

The days available on screen would be rearranged to show more or less days depending on the % of zoom.

The default view = 100% zoom would be the actual view of the calendar.
