Ability to adjust the scale/height of time axis for Weekly and Daily view (and week axis for Monthly view)

Allow adjusting the scale of the time axis. For example, one might want to shorten it so that more hours can be displayed on the same screen

Also, user should be able to set the default of such time axis scaling on the Calendar display settings on the right

This applies to all of the Day, Week, and Month views (for Month view, it should control the height of each week).
