- make lineitem aware of its state: clicable, enabled, expandable
- switch TimezonePicker to use paged list pattern
- make action bar span the full width, so the home/back button can be customized
- add checkbox line item type
- customize switch and seekbar
- many other UI tweaks

Test: manually tested
