00:36 Hack 1.4 + Redeem Codes

New:
- You can now add the timers to the list even if the timer is running. (But you can't edit them; you'll have to stop the timer for that.)
- Added a label indicating how many timers and breaks you're scheduled.
- Added a review popup after completing the list a bunch of times. Please review the app; every review helps!

Improved:
- When there's no timer running, the large timer shows '-:--' instead of '...'.
- The large timer label will be partly greyed out when the time left is below 1 minute, to help your eyes focus on the numbers that matter.
- Improved visual layout of the timer screen so that it's clearer the list of timers can be scrolled.
- Interface elements no longer disappear when you start the timer.

Fixed:
- Fixed that the screen would sometimes still dim even though you've enabled the metronome.

- Added to settings: enable or disable lowering the volume of other audio sources (eg. music) while 00:36 is open.
- Fixed the default timer settings not saving and being applied to the default timer buttons.
- Fixed the seconds part of the stopwatch occasionally incorrectly showing '60'.

- The app should now allow you to turn on music in the background.
- Added Start and Stop commands.
- Improved timer, metronome, and instruction call out behaviour going in and out of the app.
- Fixed each timer item's minus button not appearing after stopping the timer.
- Fixed notifications still showing up while in the app.

- Major improvements to partner instructions.
- The app now uses a tabbed structure as opposed to screen swiping.

- fixed 'default seconds' settings not being immediately reflected on the 'add break and timer' buttons.
