Pill Case 2 remix - even more customizable

Really liked the original and the original maker's update, but decided to take it one step further:
- Optional build plate display (using build_plate library)
- View selection from customizer pane - Lid, Body, Print or Fit
- Ability to label sections with text instead of numbers (eg. days of week)
- Improved the detents to get a more solid feel when centered on a compartment
- Corrected error in lid splits that was keeping detents from working right
- Added optional "hidden" center compartment

Some of these changes were prompted by a need to carry daily medications when I travel. The extra center compartment is great when you're going to be gone a day or two more than a week and don't want to carry a second pill box.
